CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Continuation of U.S. patent application Ser. No. 14/603,353, fled Jan. 22, 2015, which claims the benefit of priority to U.S. Provisional Patent Application No. 61/930,262, filed on Jan. 22, 2014, which are hereby incorporated by reference in their entirety.

TECHNICAL FIELD

This disclosure relates to medical devices configured to monitor biological parameters non-invasively and to provide therapeutic applications of drugs at the skin on, over, or adjacent to an Abreu brain thermal tunnel (ABTT) terminus.

BACKGROUND

Drugs are administered by several routes, including subcutaneously, orally, intramuscular, intravenously, and transdermally. Each of these approaches includes drawbacks when considering the effectiveness and side effects of the drug. With the blood-brain barrier serving to keep unwanted substances out of the brain, current methods of administering anesthesia and certain other drugs require that a very large dose of the compound be injected into the blood stream so that the drug is received by the brain. As the drug travels throughout the body, the drug may be absorbed by parts of the body not intended to intended to be exposed to the drug, sometimes resulting in severe and adverse side effects.

Oral ingestion wastes drugs because of the passage of the drugs through the digestive system, in addition to the drugs being subject to first-pass metabolism where there is a reduced effectiveness caused by liver enzymes. In addition, these compounds may take a long time to produce the desired effect when administered orally.

Injection allows therapeutic agents to bypass the effects of metabolism, but injections are painful and carry the risk of infection, besides producing large amounts of hazardous waste, e.g., used needles contaminated with body fluid.

In addition to the drawbacks described elsewhere herein, conventional methods administer drugs in locations that are remote from the brain, where portions of the pharmacological effects are realized in the body, though the desired effect is in the brain.

In order to remove dependence on needles and invasive administration, a method of transdermally introducing chemical compounds into the bloodstream via intact skin is known. Transdermal administration delivers drugs or other chemicals through the skin to local tissue, and then into the systemic circulatory system without cutting or penetration of the skin. Using transdermal methods rather than injections reduces pain, biohazardous waste, and risk of infection. Currently, transdermal delivery systems have been proposed or developed for a variety of drugs or therapeutic agents to treat many conditions and diseases.

While transdermal delivery of drugs presents many potential benefits and wide applications, its development is limited due to the biological nature of the skin, which presents a barrier to penetration because the low permeability of the skin limits the application of transdermal delivery. The transdermal flux of a drug depends on the diffusion coefficient of the drug; the thickness of the epidermis and dermis, and the condition of the skin at the application site; and the concentration gradient across the skin.

Passive transdermal delivery methods comprise the use of patches that contain a drug, and often a permeation enhancer. The structure of transdermal delivery patches generally comprises an outer layer, a middle layer that contains the drug, and a liner and/or a release liner that protects the adhesive layer, which is removed prior to use.

As briefly described above, transdermal delivery of active agents is generally executed in an area of the body that is remote from the brain or active control center that is affected by the drug being introduced into the body such as, for example, the arm, buttock, back, or leg. All of the areas currently used for transdermal delivery have a great deal of adipose tissue, i.e., fat, which serves as a significant barrier to transdermal delivery of therapeutic agents. These sites present limitations to the transdermal delivery methods, as a high dosage must be used to ensure that an effective dose reaches the control center designed to be treated by the drug. Excess drugs and active agents circulating throughout the body may be absorbed by organs and tissues not intended to be treated, thus resulting in an increased risk for damaging side effects. For this reason especially, transdermal delivery is extremely limited or impossible for use with potent drugs.

SUMMARY

This disclosure provides a series of interfaces. The interface may comprise a layer facing the ABTT skin that includes an adhesive having pores, holes and the like. Adjacent to this adhesive layer is a medication-containing layer or alternatively a reservoir housing medication. In an exemplary embodiment, the present disclosure includes an interface having a reservoir housing an absorbent material such as a sponge, a pad, a gel, and the like, said absorbent material being soaked with a solution of a medication, said absorbent material preferably being compressible. It is understood that the reservoir may include liquid, solution, cream, paste, and the like, or a combination thereof. In another embodiment, the aforementioned medication is applied through a membrane-like surface. It is also understood that the interface does not need to have an adhesive layer facing the skin and is positioned against the skin without adhesive by means of a mechanism applying pressure. Medication referred herein includes any chemical compound.

In an exemplary embodiment, the interface contacts the skin of the ABTT and may include additional adjacent areas, wherein medication is administered through a layer in contact with said skin of the ABTT. In another exemplary embodiment, the interface contacts the skin overlying the veins associated with the ABTT and may include adjacent areas, as disclosed herein, wherein medication is administered through a layer in contact with said skin. In another exemplary embodiment, the interface contacts a combination of the skin of the ABTT and the skin overlying the veins associated with the ABTT and may include adjacent areas. In exemplary embodiments, the adjacent areas range from greater than zero to 35 mm from the center of the ABTT.

The dimensions of the interface in contact with the skin prevent unwanted thermal stimulation of the skin and also prevent delivery of medication away from the target areas, namely the ABTT skin and/or skin overlying the veins associated with the ABTT. By isolating the area, the effect of the medication is increased and side effects are decreased or eliminated.

In one exemplary embodiment, the interface may comprise a multi-layer structure, including an outer layer that can function as a water repellent. In one exemplary embodiment, the interface may include an adjustable arm, said adjustable arm being preferably connected to a frame, including but not limited to a frame of eyeglasses, goggles, eye mask, head-gear, neck-gear, and the like. It should be understood that the arm may be connected by a support structure having an adhesive surface, said adhesive functioning as an anchoring means, not as a drug delivery means. The arm is constructed of suitably flexible materials, so as to be able to bend and be positioned against the ABTT skin.

In one exemplary embodiment, the interface can have any shape, including, but not limited to, oval, rectangular, square, oblong, and the like. In another exemplary embodiment, the interface can further include a releasable liner.

In one exemplary embodiment, the interface is constructed with at least one outer impermeable layer such as polyethylene, polyester, and the like.

In one exemplary embodiment, the adhesive surface includes medical grade adhesive, pressure sensitive adhesive, and the like.

In one exemplary embodiment of the interface, the medication is preferably contained in a mid-portion bordered by an outer cover or layer.

In one exemplary embodiment, the support device may include a flexible circuit and thermoelectric devices preferably spaced from each other.

The interface includes a surface that is permeable to allow diffusion of the medication.

By having an interface that relies on pressure mechanisms, the present disclosure provides embodiments that eliminate the drawbacks and limitations of using adhesives, such as discomfort, skin maceration, residues on the skin after removal and the like.

Advantages and features of the embodiments of this disclosure will become more apparent from the following detailed description of exemplary embodiments when viewed in conjunction with the accompanying drawings.

DETAILED DESCRIPTION

The present disclosure arises from the discovery that an Abreu brain thermal tunnel or ABTT provides the first known structure for brain-surface thermodynamic communication and thermal connection directly with the center of the brain. Anatomically and physiologically speaking, and as shown in FIGS. 1-3, ABTT 12 includes a continuous, direct, and undisturbed connection between a brain core 24 at the control center of the brain and the skin of ABTT terminus 10. The skin of ABTT terminus 10 is unique in that it is the thinnest skin with the fewest layers, a fat layer is absent, and has the high thermal conductivity of any skin on the human body.

The physical and physiological events at one end of the tunnel are reproduced at the opposite end. ABTT 12 enables the direct transfer of inputs to ABTT 12 to brain core 24 without significant barriers, as described in co-pending U.S. patent application Ser. No. 14/512,421, filed on Oct. 11, 2014, incorporated by reference herein in its entirety. Accordingly, the present disclosure describes apparatus, systems, devices, mechanisms, and methods that use ABTT terminus 10 and ABTT 12 to delivery compounds, chemicals, medications, biologics, such as vaccines and genes, and drugs to the brain core.

Anatomy shows the convergence of four veins at ABTT target area 10: frontal 14, superior palpebral 16, supraorbital 18, and angular 20. As angular vein 20 extends further from ABTT 12, it transitions into facial vein 22. Having converged, the blood from these veins flows toward brain core 24 from ABTT target area 10 between an eye 31 and the eyebrow into the center of the brain, which is the temperature center present in the hypothalamus or thermal storage area of the body present in the cavernous sinus. From the thermal storage area, blood is distributed throughout the brain tissue and the body, and may be used to effectively and efficiently treat and/or prevent medical conditions by the transmission of medications, chemicals, and compounds to the brain.

FIGS. 1, 2A, and 2B show the approximate location of these veins in relation to other facial features. Angular/facial vein 20/22 runs up alongside nose 26, superior palpebral vein 16 runs along eyebrow 28, and frontal vein 14 and supraorbital vein 18 run through forehead 30. Delivery of medication to these veins, and particularly ABTT terminus 10, provides a path between the skin and brain core 24 with the least barrier or resistance to drug transport identified in the human body. For the purposes of disclosure, terminology referring to relevant facial areas or veins herein will be described as one or more of the above-referenced veins and ABTT target area 10.

As described herein, veins 14, 16, 18, 20, and 22 converge in the superomedial orbit in the region of the upper eyelid and adjacent to the bridge of the nose, and flow directly, without inhibition, to the center of the brain. The skin in this area, as shown in pending application by the Applicant, is the thinnest skin in the body and free of fat, providing thereby the area most permeable to administering drugs, and by being in direct communication with the brain, the most direct path for drug delivery to the brain. These vessels lack valves, which are typically an important barrier to flow and direct transmission of pharmacologically agents. Without valves, these blood vessels truly provide a direct, uninhibited passage for transporting therapeutic agents directly to the hypothalamic region of the brain. Moreover, ABTT 12 includes a superior ophthalmic vein (SOV) 23, which connects the skin surface to the brain and corresponds to the central portion of the tunnel (ABTT 12), is valveless and has bidirectional blood flow. The SOV lies directly underneath the skin of the superomedial orbit, between eye 31 and eyebrow, and is a direct conduit from surface to the brain to the hypothalamus. The hypothalamic region of the brain is the link between the central nervous system and the endocrine system and, as such, acts as the center of control for many basic bodily functions such as, for example, hunger, thirst, body temperature, fatigue, blood pressure, immune responses, circadian cycles, hormone production and secretion, and many others.

As shown in, for example, FIG. 2B, the facial end of ABTT 12, herein referred to as a target area, or terminus 10 on the skin on, over, or adjacent to ABTT 12, measures about 11 mm in diameter measured from the medial corner of eye 31 at the medial canthal tendon and extends superiorly for about an additional 6 or 7 mm in an ABTT superior projection 11, and then extends into an upper eyelid 15 in a horn-like projection 13 for another 22 mm. ABTT terminus 10 is absent fat, and ABTT superior project 11 and horn-like project 13 are absent fat in areas near to ABTT terminus 10, with a fat layer present in areas a spaced distance away from ABTT terminus 10. It should be understood that the dashed lines in FIG. 2B represent features under the skin, and facial features are shown for approximate reference.

ABTT target area 10, as described herein, provides a direct link to the control center of the brain, since the skin of ABTT target area 10 is free from adipose tissue and other barriers. Because the blood vessels carrying blood into the brain are superficial and lie just under the top layer of thin skin, ABTT target area or terminus 10 is the ideal location for transdermal delivery to occur. In fact, the direct flow to the brain may allow doses of drugs and other chemical compounds delivered transdermally to be reduced drastically. These lower doses may, in turn, reduce the side-effects involved with many drugs, decrease waiting time before the effects of a drug are noticed, increase effectiveness of certain drugs, and remove the necessity for invasive and painful use of needles. Also, transdermal delivery of many drugs may no longer need to be carried out remotely. Since drugs can reach the hypothalamus and brain directly, the apparatus and method of the present disclosure may be used for treatment of numerous diseases and conditions that are regulated by the center of the brain such as, by way of illustration, but not of limitation, Alzheimer's disease, Parkinson's disease, thyroid conditions, seizures, pain, and hunger. Examples of drugs that may be administered using this method are contraceptives, anesthesia, antibiotics, narcotics, any hormonal associated drugs, cancer agents, and any drug to treat any condition or disease.

The present disclosure concerns a device, apparatus, or mechanism and method for transdermally delivering drugs and other chemical compounds or therapeutic agents through the skin of ABTT target area 10.

In one example of an application of the present disclosure, as carried out in a research setting, a patch designed to transdermally deliver melatonin (MEL] through the skin of ABTT target area 10 was shown to provide an intended therapeutic effect. Oral introduction of MEL is suggested to elevate plasma MEL and reduce waking after sleep onset by promoting sleep in the latter part of an 8-hour sleep opportunity. MEL has been shown to improve daytime sleep, but the hormone's short elimination half-life limits its use as a hypnotic in shift workers and individuals with jet lag or other sleep problems. As a solution to this problem, MEL was applied transdermally on the skin of ABTT target area 10 using a patch that contained, in a solvent formulation, water, propylene glycol, lauric acid, and hydroxypropylcellulose, and also comprised a non-rate-limiting membrane designed to have active contact with an area 1.0 cm². Experiments show that ABTT terminus 10 and the dose were best suited to produce the intended plasma profile for clinical effect. It should be understood that any type of membrane or porous material can be used in accordance with the principles of the present disclosure.

In the present disclosure, the terms therapeutic agent, medication, compound, and drug are used to describe any compound, molecule, solution, element or other chemical intended to be intentionally presented into the body to provide an intended benefit. Most often, the present disclosure is intended for use in conjunction with drugs prescribed by a doctor or the like and intended to treat a certain condition such as, for example, pain or a disease. However, it should be understood that the present disclosure is not limited to the examples herein or for use with common drugs or to treat specific diseases. For example, although it may not be preferred, the present disclosure may be used in conjunction with any chemical compound to include even drugs such as cocaine, cannabis, lysergic acid, amphetamines, and the like.

Some exemplary embodiments of the present disclosure are intended for the transdermal delivery of drugs, therapeutic agents, or other chemical compounds into the body through ABTT target area 10 using the teachings of the exemplary embodiments of the present disclosure.

In an exemplary embodiment, a passive type apparatus of the present disclosure in an exemplary embodiment includes a housing containing a drug or other compound that has a protective backing and is adapted to be secured to ABTT target area 10, which in an exemplary embodiment may be accomplished by using an adhesive material, such as a patch delivery method described in detail herein. The patch may be configured for one-time use to deliver a single dose of medication or it may comprise a liner that is adapted to release a specific amount of compound over an extended period of time, or to release several doses of medication over a further prolonged period of time. In alternate embodiments, the passive apparatus may also employ the use of any permeation enhancers or other topical passive permeation methods as described in detail herein. The patch can also be reusable and used for certain period of time and then removed. In this embodiment, a new adhesive surface may be used to secure the patch to the skin. The chemical compound can also be replaced once the original compound has been delivered to the skin in its entirety.

As described herein, the present disclosure describes apparatus, devices, mechanisms, systems, and methods of delivering compounds, chemicals, and drugs to the brain core. For the sake of simplicity, all substances deliverable to the brain core are described herein as “drugs.” Generally, devices for delivering drugs through ABTT terminus 10 can be categorized as passive devices, which operate by the presence of the drug on the skin of ABTT terminus 10 and/or associated veins 14, 16, 18, 20 and 22, or active devices, which include one or more features to control drug delivery to ABTT terminus 10 and/or associated veins 14, 16, 18, 20 and 22, or to control drug flow through ABTT terminus 10 and/or associated veins 14, 16, 18, 20 and 22. Generally, the configurations and dimensions shown for passive transdermal devices can be applied to active transdermal devices, and vice versa, when an active or passive embodiment can be configured with such configurations and dimensions, unless otherwise specified.

Passive transdermal delivery devices are configured to deliver precise amounts of drugs to ABTT terminus 10 and/or the skin over associated veins 14, 16, 18, 20, and 22, for permeation through the skin at ABTT terminus 10 and/or associated veins 14, 16, 18, 20, and 22, and subsequent transmission through ABTT 12 to brain core 24. While the various embodiments of transdermal delivery devices disclosed herein bear similarity to conventional passive transdermal patches, a plurality of differences exist, as will be understood by a person of ordinary skill in that art reading and applying the teachings of the present disclosure.

Many aspects of the disclosure are described in terms of sequences of actions to be performed by elements of a computer system or other hardware capable of executing programmed instructions, for example, a general purpose computer, special purpose computer, workstation, or other programmable data processing apparatus. It will be recognized that in each of the embodiments including active or electronic elements, the various actions could be performed by specialized circuits (e.g., discrete logic gates interconnected to perform a specialized function), by program instructions (software), such as logical blocks, program modules etc. being executed by one or more processors (e.g., one or more microprocessors, a central processing unit (CPU), and/or application specific integrated circuit), or by a combination of both. For example, embodiments can be implemented in hardware, software, firmware, middleware, microcode, or any combination thereof. The instructions can be program code or code segments that perform necessary tasks and can be stored in a non-transitory, machine-readable medium such as a storage medium or other storage(s). A code segment may represent a procedure, a function, a subprogram, a program, a routine, a subroutine, a module, a software package, a class, or any combination of instructions, data structures, or program statements. A code segment may be coupled to another code segment or a hardware circuit by passing and/or receiving information, data, arguments, parameters, or memory contents.

The non-transitory machine-readable medium can additionally be considered to be embodied within any tangible form of computer readable carrier, such as solid-state memory, magnetic disk, and optical disk containing an appropriate set of computer instructions, such as program modules, and data structures that would cause a processor to carry out the techniques described herein. A computer-readable medium may include the following: an electrical connection having one or more wires, magnetic disk storage, magnetic cassettes, magnetic tape or other magnetic storage devices, a portable computer diskette, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (e.g., EPROM, EEPROM, or Flash memory), or any other tangible medium capable of storing information.

It should be noted that the systems of the present disclosure are illustrated and discussed herein as having various modules and units which perform particular functions. It should be understood that these modules and units are merely schematically illustrated based on their function for clarity purposes, and do not necessarily represent specific hardware or software. In this regard, these modules, units and other components may be hardware and/or software implemented to substantially perform their particular functions explained herein. The various functions of the different components can be combined or segregated as hardware and/or software modules in any manner, and can be useful separately or in combination. Input/output or I/O devices or user interfaces including but not limited to keyboards, displays, pointing devices, and the like can be coupled to the system either directly or through intervening I/O controllers. Thus, the various aspects of the disclosure may be embodied in many different forms, and all such forms are contemplated to be within the scope of the disclosure.

Basic passive transdermal delivery devices are shown in FIGS. 4-6. A first configuration of a passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure is shown in FIGS. 4 and 6, indicated generally at 32. In the embodiment of FIG. 4, passive device 32 includes a first portion 34, which may also be described as a drug container or reservoir, and a second portion 36, which may also be described as a border or edge.

Device 32 is configured to include dimensions that are optimized for interfacing with ABTT terminus 10. In an exemplary embodiment, device 32 is configured with a device diameter 38 of less than or equal to about 25 mm. In this exemplary embodiment, drug container 34 includes a diameter 40 of less than or equal to 15 mm. However, in another exemplary embodiment, drug container diameter 40 can also be less than or equal to 10 mm, and in yet another exemplary embodiment, drug container diameter 40 can be less than or equal to 7.5 mm. In yet another exemplary embodiment, device diameter 38 can be less than or equal to 30 mm, and drug container diameter 40 can be less than or equal to 20 mm, less than or equal to 15 mm, less than or equal to 10 mm, or less than or equal to 7.5 mm. In a further exemplary embodiment, device diameter 38 can be less than or equal to 20 mm, and drug container diameter 40 can be less than or equal to 10 mm, or less than or equal to 7.5 mm. In yet a further exemplary embodiment, device diameter 38 can be less than or equal to 10 mm, and drug container diameter 40 can be less than or equal to 2.5 mm. The area outside drug containing area 34 is referred as an edge or border 41, and the dimension of edge or border 41 is associated with the strength of the adhesive. Therefore, an edge with a strong adhesive can be made very small, such as including a width that is equal to or less than 1 mm, for example, and in this embodiment drug containing area 34 can have a diameter (or largest dimension) in a range from 1 mm to 40 mm. It should be noted that the whole surface area (identified as diameter 38) can be covered by an adhesive surface, with the drug disposed behind this surface, and in this embodiment the whole area contains drug and there is not a separate edge with adhesive.

Dimensions of the surface containing drug of the embodiments of the present disclosure can be made smaller as compared to traditional patches or devices because less drug is necessary since ABTT terminus 10 area has the highest permeation rate of the body and there is a direct communication with the blood vessels and direct path to the brain.

The larger diameter 40 of drug container 34 becomes, the easier it is to assure drug placement on ABTT terminus 10. However, the larger diameter 40 becomes, the more uncontrolled delivery of drugs becomes. Accordingly, smaller diameters 40 are preferred for controlled, efficient delivery of drugs located in drug container 34 to ABTT terminus 10. However, a minimum diameter 40 is preferred because the diameter of ABTT terminus 10 is approximately 3 mm to 11 mm, used to define the diameter, and as will be seen, beyond ABTT terminus 10 a layer of fat under the skin reduces the flow rate of drugs into ABTT 12.

The larger diameter 38 of device 32 becomes, the easier it is to handle and place device 32. However, diameter 38 is practically determined by an adjacent eye of a patient or subject, since ABTT terminus 10 is very near to the eye, and most patients or subjects object to the placement of objects on or over the eye. Accordingly, a smaller diameter 38 is preferred for patient comfort, but the smaller diameter 38 becomes, the more difficult it is to handle and place device 32.

FIG. 6 shows an exemplary cross section of device 32 of FIG. 4. Device 32 includes at least a backing or support layer 42 on which is positioned, either directly or indirectly, a protective layer 44. A drug 46 is positioned directly between protective layer 44 and backing layer 42. Protective layer 44 and backing layer 42 may be configured to be impermeable to drug 46, or additional layers may be provided in device 32 to protect protective layer 44 and backing layer 42 from drug 46, or to control flow of drug 46 out of device 32. In an exemplary embodiment, an adhesive layer 48 is also positioned between protective layer 44 and backing layer 42. Adhesive layer 48 is configured to secure device 32 to a patient or subject's skin to permit drug 46 to be directly in contact with the patient or subject's skin to permit the permeation of the skin by drug 46. In an exemplary embodiment, drug 46 is infused into adhesive layer 48, and removal of protective layer 44 exposes adhesive layer 48 and drug 46 such that an exemplary device 32 is configured to be secured to a patient or subject's skin across the entirety of device 32 by adhesive layer 48.

In the exemplary embodiment of FIG. 7, device 32 is configured to include a convex curvature 50. Curvature 50 is configured to be an approximate match to the unique curvature of the face at ABTT terminus 10. It should also be understood that each of the disclosed embodiments can or does include a similar curvature to match the area on and adjacent to ABTT terminus 10. It should also be understood that a flat patch or device, including a conventional flat patch or flat bandage are within the scope of the invention. A flat patch or flat device includes flexible areas, or can be flexible in its entirety so as to conform to the geometry and shape of the ABTT terminus 10.

FIG. 5 is a view of another passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 52. Device 52 is configured to be approximately square in a plan view. Similar to device 32, device 52 includes a first portion 54, which may also be described as a drug container or reservoir, and a second portion 56, which may also be described as a border or edge.

Similar to device 32, device 52 is configured to include dimensions that are optimized for interfacing with ABTT terminus 10. In an exemplary embodiment, device 52 is configured with a device width 58 and a device length 60, each of which is less than or equal to about 35 mm. In this exemplary embodiment, drug container 54 includes a container width 62 and a container length 64, each of which is less than or equal to 25 mm. However, in another exemplary embodiment, container width 62 and a container length 64 can each also be less than or equal to 10 mm, and in yet another exemplary embodiment, container width 62 and container length 64 can each be less than or equal to 7.5 mm. In yet another exemplary embodiment, device width 58 and device length 60 can each be less than or equal to 30 mm, and container width 62 and container length 64 can each be less than or equal to 20 mm, less than or equal to 15 mm, less than or equal to 10 mm, or less than or equal to 7.5 mm. In a further exemplary embodiment, device width 58 and device length 60 can each be less than or equal to 20 mm, and container width 62 and container length 64 can each be less than or equal to 10 mm, or less than or equal to 7.5 mm. In yet a further exemplary embodiment, device width 58 and device length 60 can each be less than or equal to 10 mm, and container width 62 and container length 64 can each be less than or equal to 2.5 mm. The area outside the drug containing area is referred as edge or border 56, and the dimension of edge 56 is associated with the strength of the adhesive. Therefore, an edge with a strong adhesive can be made very small, such as equal to or less than 1 mm for example, and in this embodiment, the drug container 54 can have a container width 62 or a container length 64 measuring in a range from 1 mm to 40 mm. It should be noted that the whole surface area, identified by device width 58 and device length 60, can be covered by an adhesive surface, with the drug disposed behind this surface, and in this embodiment the whole area contains drug and there is not a separate edge with adhesive.

The larger container width 62 and container length 64 of drug container 54 become, the easier it is to assure drug placement on ABTT terminus 10. However, the larger container width 62 and container length 64 become, the more uncontrolled delivery of drugs becomes. Accordingly, smaller container widths 62 and container lengths 64 are preferred for controlled, efficient delivery of drugs located in drug container 54 to ABTT terminus 10.

The larger device width 58 and device length 60 of device 52 become, the easier it is to handle and place device 52. However, device width 58 and device length 60 are practically determined by an adjacent eye of a patient or subject, since ABTT terminus 10 is very near to the eye, and most patients or subjects object to the placement of objects on or over the eye. Accordingly, a smaller device width 58 and device length 60 are preferred for patient comfort, but the smaller device width 58 and device length 60 become, the more difficult it is to handle and place device 52.

As described herein, it should be understood that skin without fat is present under ABTT terminus 10, extending about 22 mm along the upper eyelid, and 6 to 7 mm along a line perpendicular to the eyelid, as shown in FIG. 2B, terminating at the superior edge of the eyebrow. A lower eyelid skin surface 17 with a minimal amount of fat is located along the edge of the lower eyelid, and extends about 10 mm from the edge of the lower eyelid, and is also a preferred area for administering drugs transdermally. While this area includes some fat, and does not include a vein, the numerous capillaries in this area feed veins that flow into ABTT 12, such as angular vein 20.

FIG. 7 shows another passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 66. Device 66 is configured to include a shape that is adapted to fit to the curved anatomy of ABTT terminus that may be described by many terms, including kidney, bean, banana, boomerang, comma, curvilinear, and arc. As with the configuration of FIGS. 4 and 6, a portion 68 of device 66 that is configured to interface with ABTT terminus 10 is configured with a convex curvilinear shape, on which is positioned a drug patch or reservoir 70, shown exposed in FIG. 7.

FIG. 8 is a view of a general configuration of a transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 72. Device 72 includes a first, drug container portion 74 is positioned along device 72. Device 72 includes a shape similar to device 66 shown in FIG. 7. In an exemplary embodiment, device 72 extends in an arc 76 of about 60 degrees, centered on drug container portion 74. However, in another exemplary embodiment, device 72 extends in a first arc 78 of at least 50 degrees from a center of drug container portion 74, and a second arc 80 of at least 50 degrees from a center of drug container portion 74. Device 72 further includes a first end 82, which is configured to be positioned in a region between a patient's eye and eyebrow, and a second end 84, which is configured to be positioned in a region between a patient's eye and a patient's nose. In an exemplary embodiment, first end 82 includes a first transverse width 86 positioned a first longitudinal length 88 from first end 82 along a centerline 90 of device 72, and first transverse width 86 is 15 mm±8 mm, and first longitudinal length 88 is 7.5 mm±5 mm. Also in an exemplary embodiment, second end 84 includes a second transverse width 92 positioned a second longitudinal length 94 from second end 84 along centerline 90, and second transverse width 92 is greater than or equal to first transverse width 86 and second longitudinal length 94 is approximately equal to first longitudinal length 94. The effect of these dimensions is that first end 82 is smaller in width than second end 84, giving device 72 a shape similar to an elongated and curved tear drop.

In another exemplary embodiment, device 72 can include a second end 96, shown in dashed lines in FIG. 8, and a third transverse width 98 positioned a third longitudinal distance 100 from second end 96 along centerline 90, wherein third transverse width 98 is approximately equal to first transverse width 86 and third longitudinal distance 100 is approximately equal to first longitudinal length 88. The effect of this configuration is that device 72 attains a shape more similar to a boomerang than a teardrop.

One challenge with transdermal delivery devices is assuring sufficient adherence to the skin on and adjacent to ABTT terminus 10. One solution is to provide sufficient area for adhesive on a device, such as device 72, to adhere to a patient's skin. The exemplary configuration of device 72 includes an elongated shape that extends along centerline 90 for at least twice the diameter of drug container portion 74, in addition to the diameter of drug container portion 74, for a total length along centerline 90 of at least three times the diameter of drug container portion. It should also be understood that a strong adhesive allows decreasing the dimensions of the area surrounding the drug area, as described herein.

One way to define an inner and outer dimension of a transdermal delivery device is by using two circles.

In an exemplary embodiment shown in FIG. 9, a first circle 102 including a first center or origin 104 and a first diameter 106 is overlapped by a second circle 108 including a second center or origin 110 and a second diameter 112. In an exemplary embodiment, first diameter 106 is greater than or equal to second diameter 112, with first diameter 106 being in a range 15 mm to 50 mm, and second diameter 112 being in a range 8 mm to 50 mm. Second center or origin 110 is offset from first center or origin 104 by an offset distance 114 that is determined by first diameter 106 and second diameter 112, which determines a gap or width 116 between an exterior 118 of second circle 108 and an interior 120 of first circle 102. The choices of first diameter 106, second diameter 112, and offset distance 114, along with a design position 122 for a transdermal delivery device, is determined at least partially by a desired width of a drug container or reservoir. In an exemplary embodiment, gap or width 116 will be configured to provide a drug container or reservoir width of at least 3 mm. In yet another exemplary embodiment, second diameter 112 is approximately one half first diameter 106. It should be understood that the dimensions of the drug container or reservoir can have any dimension that fits between the eye and eyebrow and that includes the ABTT terminus 10 or any of the veins 14, 16, 18, 20, and 22.

In another exemplary embodiment shown in FIG. 10, a second circle 130 including a second center or origin 132 and a second diameter 134 is positioned within a first circle 124 including a first center or origin 126 and a first diameter 128. In an exemplary embodiment, first diameter 128 is greater than or equal to second diameter 134, with first diameter 128 being in a range 10 mm to 60 mm, and second diameter 134 being in a range 5 mm to 50 mm. Second center or origin 132 is offset from first center or origin 126 by an offset distance 136 that is determined by first diameter 128 and second diameter 134, which determines a gap or width 138 between an exterior 140 of second circle 130 and an interior 142 of first circle 124. The choices of first diameter 128, second diameter 134, and offset distance 136, along with a design position 144 for a transdermal delivery device, is determined at least partially by a desired width of a drug container or reservoir. In an exemplary embodiment, gap or width 138 will be configured to provide a drug container or reservoir width of at least 3 mm. In yet another exemplary embodiment, second diameter 134 is approximately one half first diameter 128. A tear drop shape as previously described is included in this embodiment. Preferably, the whole surface of the tear drop and boomerang embodiments of FIGS. 8-10 contain drug, and in these embodiments, the drug surface includes an adhesive.

FIG. 11 is a view of a patient or subject's face 146 on which is positioned a passive transdermal delivery device 148 configured in accordance with an exemplary embodiment of the present disclosure. Transdermal drug delivery device 148 includes a drug delivery region 150 that can be larger than ABTT terminus 10, but preferably needs to be in a region 152 bounded by eyebrow 154, nose 156, and eye 158, where ABTT terminus 10 is located. Drug delivery region or portion 150, though shown in phantom lines in FIG. 11 as a circular shape, can be other shapes, such as kidney, polygonal, etc., as long as region 150 substantially overlaps ABTT terminus 10. In the context of this disclosure, substantially overlaps is preferably an overlap of ABTT terminus 10 by drug delivery region 150 of at least 80%, though an overlap as low as 50% can still provide a therapeutically effective dose in some situations. The goal in every case should be a 100% overlap of ABTT terminus 10 by drug delivery region 150.

It should be understood that the drug delivery area does not need to be exactly overlying ABTT terminus 10, but can be located adjacent to ABTT terminus 10, since drug entering the skin in the region adjacent to ABTT terminus 10 will be carried towards ABTT terminus 10. The adjacent areas vary with the location on the face. As shown in FIG. 2B, a first adjacent area 21 extends over a diameter of about 35 mm centered on ABTT terminus 10, excluding eye 31. A second adjacent area 23 extends superiorly about 25 mm from first adjacent area 21 along front vein 14. A third adjacent area 25 extends transversely or laterally about 25 mm from second adjacent area 23 along supraorbital vein 18. A fourth adjacent area 27 extends transversely or laterally about 30 mm from first adjacent area 21. A fifth adjacent area 29 extends about 30 mm along angular vein 20 from first adjacent area 21 and about 25 mm along lower eyelid skin surface 17 from first adjacent area 21. It should be understood that while application of transdermal delivery devices applied in the aforementioned adjacent areas provide drug delivery to veins or capillaries that flow into ABTT 12, the further these areas are from ABTT terminus 10, the less effective drug application becomes. Accordingly, the smallest possible distance from ABTT terminus 10 is preferred for drug delivery. Thus, while first adjacent area 21 can be 35 mm in diameter, a smaller diameter centered on ABTT terminus 10 is preferred, such as a diameter of about 30 mm, 25 mm, 20 mm, or less.

FIGS. 12 and 13 are views of a passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 160. Device 160 includes a device support 162 that serves to provide structure and support for the various elements of device 160. Device 160 further includes a drug container or reservoir 164 positioned on device support 162 in a location that locates drug container 164 over ABTT terminus 10 when device 160 is placed as shown, for example, in FIG. 11. Drug container 164 is covered prior to use by a removable or peelable layer 166, which may also be described as a release liner, which protects drug container 164 and protects people coming into contact with device 160 from the drug in drug container 164. Removable layer 166 is adhered to device 160 by an adhesive layer 168 positioned between device support 162 and removable layer 166. Removable layer 166 can be configured to include a tab 170 that is without or absent adhesive to enable a user to grasp a portion of removable layer 166 more easily to separate removable layer 166 from device 160. Once removable layer 166 is separated from device 160, the drug located in drug container 164 is exposed and ready for application to ABTT terminus 10 for transdermal delivery through ABTT terminus 10 to ABTT 12.

While drug container 164 is shown as a bubble or unified structure, it should be understood that a deliverable drug may also be infused or available in adhesive layer 168. Further, in the exemplary embodiment of FIG. 13, the drug located in drug container 164 may be activated by a separate chemical once removable layer 166 is separated from device 160. For example, alcohol, water, a liquid permeability enhancer, or another activation compound may be applied to the drug in drug container 164 prior to placement of device 160 on a patient or subject.

FIGS. 14 and 15 are views of another passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 172. Device 172 includes features that may be similar to device 160, including a support 174 that can be similar to device support 162, a drug container or reservoir 176 positioned on device support 174 in a location that locates drug container 176 over ABTT terminus 10 when device 172 is placed as shown, for example, in FIG. 11. Drug container 176 is covered prior to use by a removable or peelable layer 178 that protects drug container 176 and protects people coming into contact with device 172 from the drug in drug container 176. Removable layer 178 is adhered to device 172 by an adhesive layer 168 positioned between device support 174 and removable layer 178. Removable layer 178 can be configured to include a tab 170 that is without or absent adhesive to enable a user to grasp a portion of removable layer 178 more easily to separate removable layer 178 from device 172. Once removable layer 178 is separated from device 172, the drug located in drug container 176 is exposed and ready for application to ABTT terminus 10 for transdermal delivery through ABTT terminus 10 to ABTT 12.

Device 172 includes an absorbent layer 180 positioned between device support 174 and drug container 176. The drug located in drug container 176 may be activated by a separate chemical once removable layer 178 is separated from device 172. For example, alcohol, water, a liquid permeability enhancer, or another activation compound may be applied to the drug in drug container 164 prior to placement of device 160 on a patient or subject. However, absorbent layer 180 is configured to absorb the separate chemical and then to activate the drug by enhancing permeation, such as, for example, by adding ethanol, including by liquefying the drug, or infusing the drug with a liquid to improve permeability with skin. In the embodiment of FIG. 15, the drug may go through a phase change or soften from a portion of the drug that is away from the skin of a patient, which provides a mechanism to control the initial rate of drug flow into a patient that is different from the embodiment of FIG. 13.

FIGS. 16 and 17 are views of a passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 182.

The transdermal delivery devices disclosed herein can be a challenge to properly place for some individuals, and for those inexperienced in positioning devices on ABTT terminus 10, given its size and location. To assist in placement of the various devices disclosed herein, a notch or indicator 222 may be located to align device 220 with a facial feature, such as a corner 224 of an eye 226.

FIG. 21 is a view of another passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 228. Device 228 includes a support 230 that extends from a region 232 between an eye 234 and an eyebrow 236, over ABTT terminus 10, and then alongside a nose 238. Positioned on device support 230 is a plurality of drug containers or reservoirs 240 a-e that may be configured as round, elliptical, or elongated, as shown herein, or may be square or rectangular, as shown in FIG. 21. Device 228 can also include an alignment aid, such as an indicator 242 or notch 243. In the exemplary embodiment of FIG. 21, drug container 240 a configured to be positioned on, over, or adjacent ABTT terminus 10 when device 228 is properly positioned on a patient or subject's face 244. Drug containers 240 b-e are configured to be positioned on, over, or adjacent angular vein 20 when device 228 is properly positioned on face 244, to augment the flow of drugs into ABTT 12. Alternatively, a thermoelectric device can be included with each drug container 240 a-e, making device 228 an active device.

FIG. 22 is a perspective view of a passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 246. Device 246 includes a first, drug delivery side 248, and a second, support side 250. Device 246 further includes a removable or peelable portion that has been removed to show drug delivery side 248. In the embodiment of FIG. 22, drugs are configured to extend over most or all of first, drug delivery side 248. The configuration of device 246 increases the likelihood of placement of device 246 over ABTT terminus 10, though some drugs may permeate areas of a patient or subject's face that are less effective than ABTT terminus 10. FIG. 23 is a view of device 246 positioned on a patient or subject face 252.

FIG. 24 is a side view of a patient's face on which are positioned a plurality of passive transdermal delivery devices in accordance with an exemplary embodiment of the present disclosure. A first transdermal delivery device 254, which may be similar or identical to any of the transdermal delivery devices configured to be positioned on ABTT terminus 10, shown in phantom lines in FIG. 24, and compatible with the other transdermal delivery devices associated with this embodiment, is configured to be positioned to deliver drugs to ABTT terminus 10, at least a portion of superior palpebral vein 16, shown in phantom lines in FIG. 24, and at least a portion of angular vein 20, also shown in phantom lines in FIG. 24. A second transdermal delivery device 256 is positioned on the skin along and over at least a portion of frontal vein 14 and/or supraorbital vein 18, shown in phantom lines in FIG. 24. A third transdermal delivery device 258 is positioned along and over at least a portion of angular vein 20. As has been described herein, frontal vein 14, superior palpebral vein 16, and angular vein 20 all feed into ABTT 12, shown in phantom in FIG. 24, and then into the core of the human brain. While ABTT terminus 10 provides a unique location for transdermal delivery of drugs given the lack of fat, and the minimal thickness of the skin in this location, the amount of drugs needed may be such that transdermal delivery to ABTT terminus 10 only is insufficient for a therapeutically effective dosage, in the event that a large amount of drugs need to be administered or when there is a need for extended period for drug release. Accordingly, additional drugs can be delivered to ABTT 12 by way of veins 14, 16, 18, and 20/22, all of which make use of the direct connection of these veins to ABTT 12 and the core of the brain. In these embodiments, the drug delivery device may lie adjacent to the nose when overlying angular vein 20, below the nose when overlying facial vein 22, between the eyebrow and on the forehead when overlying the frontal vein 14, along the inferior edge of the eyebrow, in the region of the upper eyelid, when overlying the superior palpebral vein 16, and along the superior edge of the eyebrow on the forehead region when overlying the supraorbital vein 18. The additional drug delivery devices provide an increased quantity of drugs, and because the permeation rate is lower through the skin over veins 14, 16, 18, and 20/22, the drugs in devices in those locations provide drugs for a longer period.

FIG. 25 is a view of a patient or subject's face 260 with a passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure positioned thereon, indicated generally at 262. Device 262 is configured as a triangular shape, and is configured to include a drug delivery region or portion 264 that extends over substantially the entire surface of device 262. In the context of this embodiment, substantially is at least 90% of the surface of device 262. Though an arc, banana, bean, etc., shape, such as that shown in FIG. 23, provides a relatively good match with the unique geometry of the face around ABTT terminus 10, other shapes can also provide an acceptable match with this geometry, such as a triangle. The triangular shape of device 262 is configured to extend into a first region 266 between an eyebrow 268 and an eye 270, and into a second region 272 between a nose 274 and eye 270.

FIG. 26 is a view of face 260 with another passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure positioned thereon, indicated generally at 276. Device 276 is triangular, similar to device 262, and is positioned generally in the same location as device 262. However, device 276 is configured to include a drug delivery container, reservoir, or region 278 that is configured to be positioned on, over, or adjacent to ABTT terminus 10 when device 276 is properly positioned on face 260. Additionally, drug delivery container 278 is sized and dimensioned to be the approximate size of ABTT terminus 10. Device 276 is further configured to include a notch or indicator 280 to assist with the positioning of device 276.

FIG. 27 is a view of face 260 with yet another passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure positioned thereon, indicated generally at 282. Device 282 is configured with a triangular portion 284 on the portions of device 282 that extend along eyebrow 268 and nose 274, and an arced portion 286 on the portions of device 282 that extend along eye 270. Thus, exemplary transdermal delivery devices may combine the geometry of more than one embodiment disclosed herein effectively to take advantage of the various disclosed embodiments. Device 282 further includes a drug container, reservoir, or delivery portion 288 that extends over substantially an entire side of device 282 that interfaces with the skin of face 260 in an area around ABTT terminus 10.

FIG. 28 is a view of a patient or subject's face 290 with a further passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure positioned thereon, indicated generally at 292. Device 292 includes a drug container or reservoir 294 configured to be positioned on ABTT terminus 10. Device 292 includes a shape that can be described as elongated or elliptical, with drug container 294 positioned closer to a first end 296 of device 292 than a second end 298 of device 292. Device 292 extends downwardly on face 290 alongside a nose 300 in a region 302 between nose 300 and an eye 304.

FIG. 29 is a view of face 290 with a still further transdermal delivery device in accordance with an exemplary embodiment of the present disclosure positioned thereon, indicated generally at 306. Device 306 is configured to extend along a region 308 located between eye 304 and an eyebrow 310. Device 306 includes a first portion 312 that is approximately rectangular in shape and a second portion 314 that includes a triangular shape configured to extend into a corner region 316 bounded by eyebrow 310, nose 300, and eye 304. Device 306 includes a first drug container 318, a second drug container 320, and a third drug container 322, all of which are shown with hidden lines, extending along the longitudinal length of device 306. First drug container 318 is configured to be positioned on ABTT terminus 10. Second drug container 320 and third drug container 322 are configured to be positioned on a portion of superior palpebral vein 16 when device 306 is located on face 290. Device 306 may include a single removable or peelable portion, or it may include a plurality of removable portions, with at least one portion associated with at least one drug container. The benefit of such a configuration is that it permits significant variation in drug doses to be applied to the face for delivery into ABTT 12.

FIG. 30 is a plan view of a passive transdermal delivery device configured to simultaneously delivery two different drugs, in accordance with an exemplary embodiment of the present disclosure, indicated generally at 324. Device 324 is configured with a first drug delivery container 326 and a second drug delivery container 328, both of which are configured to be positioned over ABTT terminus 10 at the same time. When a removable strip (not shown) is separate from device 324, the drugs in first container 326 and second container 328 are available to be positioned in contact with the skin of a patient or subject. First container 326 and second container 328 can be identical in size with a different skin permeability, effectively modifying the ratio of drugs delivered to a patient or subject's ABTT 12. First container 326 and second container 328 can be configured to have different cross-sectional areas, as shown in FIG. 30, with approximately the same skin permeability, which then delivers two different quantities of the drugs in first container 326 and second container 328 through the skin of a patient into ABTT 12. It should be understood that by selecting a combination of cross-sectional areas and skin permeability, an infinite number of ratios of drug delivery can be configured for delivery through the skin of ABTT terminus 10. A configuration such as that of device 324 is beneficial for delivery of at least two drugs simultaneously, which is desirable for certain medical conditions. It should be understood that one container may have a permeation enhancer and a second container may have a drug, the permeation enhancer being released first by virtue of permeability of a membrane holding the permeation enhancer, followed by the drug release.

FIGS. 31-33 are views of a passive transdermal delivery device with extended drug delivery capability in accordance with an exemplary embodiment of the present disclosure, indicated generally at 330. Device 330 includes a support 332 on which is positioned a spacer layer 334 that is configured with cutouts to define a first volume 336, located in a first portion 337, and a second volume 338 located in a second portion 339. First portion 337 is connected to second portion 339 by connection portion 341. A cover layer 340 is positioned over spacer layer 334 and is configured to cover second volume 338 while leaving first volume 336 open. A removable or peelable layer 342 is configured to cover and protect first volume 336, along with an adhesive layer 344 positioned between removable layer 342 and cover layer 340. Removable layer 342 may include a tab 346 that extends beyond device 330 to enable grasping of removable layer 342 to remove layer 342. An absorbent material 348 is positioned in first volume 336 that readily absorbs a drug for transdermal delivery. A drug 350 is located in second volume 338, which serves as a feeder reservoir to absorbent material 348 in first volume 336. Drug 350 may be inserted or enter through an opening 352 formed in spacer layer 334, and opening 352 can then be closed by a plug 354. Device 330 can be configured to include a flow control membrane 356 positioned between feeder reservoir 338 and absorbent material 348. Flow control membrane 356 moderates the rate of flow from feeder reservoir 338 to absorbent material 348. Absorbent material 348 can be configured to include a protruding portion 358 that extends beyond an outer plane 360 of adhesive layer 344. Protruding portion 358 assures contact with the skin of ABTT terminus 10 when removable layer 342 is separated from device 330.

Device 330 is configured to provide an extended duration of drug delivery to ABTT terminus 10. Such extended duration is provided by feeder reservoir 338, and the rate of delivery to absorbent material 348, which can be moderated or modified by flow control membrane 356. The flow from feeder reservoir 338 to absorbent material 348 is possible because feeder reservoir 338 is configured to be positioned at a location on a patient higher than absorbent material 348, such as a forehead of a patient, as shown in FIG. 33. Reservoir 338 feeds liquid drug 350, by gravity, into first volume 336 positioned over ABTT terminus 10, where drug 350 permeates absorbent material 348 until drug 350 reaches ABTT terminus 10.

While most of the drug delivery devices described to this point are considered passive delivery devices, even a passive delivery device can be configured to include enhanced delivery features. One such passive transdermal delivery device is shown in FIG. 34 and indicated generally at 362. Device 362 includes a first layer 364, an adjacent second layer 366, and another adjacent third layer 368, which define an internal volume 370. Internal volume 370 is enclosed by a removable layer 372 at one end, and a cover layer 374 at a second end opposite the first end.

An absorbent material 376 containing a skin-permeable drug is positioned adjacent to removable layer 372 and is exposed when removable layer 372 is separated from device 362. A flexible, impermeable membrane 378 separates absorbent material 376 from the portion of internal volume 370 that is adjacent the second end of internal volume 370. Flexible, impermeable membrane 378 is attached to at least one of first layer 364 and second layer 366 or is captured between first layer 364 and second layer 366, which can then be secured to each other by an adhesive or other fastening apparatus. A slide plate 380 is positioned in a slot 382 formed in at least one layer, or formed between, for example, second layer 366 and third layer 368, which then divides internal volume 370 into a lower volume 384, which is configured to contain absorbent material 376, and an upper volume 386.

A spring 390 and a pressure plate 388 are positioned in upper volume 386, exerting force on slide plate 380. When slide plate 380 is pulled from device 362, the force of spring 390 causes pressure plate 388 to move toward flexible impermeable membrane 378, placing pressure on membrane 378 and, consequently, absorbent material 376. The pressure placed on absorbent material 376 forces the drug in absorbent material 376 to move outwardly, toward the skin of ABTT terminus 10 when device 362 is properly positioned to locate absorbent material 376 on, over, or adjacent the skin of ABTT terminus 10. It should be understood that other fastening apparatuses, devices, or mechanisms can be used to position device 362 on the skin of ABTT terminus 10, such as an annular structure, a structure connected to a frame, and the like, which positions and presses absorbent material 376 against the skin, and in those embodiments there is no need for an adhesive surface area.

A stretchable or adjustable strap 416 is configured to secure flexible plate 414 on a patient's forehead, also providing the force needed to maintain drug container 396 in contact with ABTT terminus 10.

FIGS. 38 and 39 are views of a support apparatus and passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated at 418 and 420, respectively. Support apparatus 410 includes one or more straps 422 for securing support apparatus 410 to a subject or patient's head. Straps 422 can be configured to be flexible or adjustable. Support apparatus 410 further includes a flexible plate 424 configured to support a vertically-extending support arm 426. One or more angled braces 428 can connect vertically-extending support arm 426 to plate 424 to provide rigidity to support arm 426. Flexible plate 424 is configured to include a pocket 430 formed by a clear sheet 432. A sheet 434 including a label for a drug being applied by delivery device 420 can be inserted into pocket 430 for view by an external observer, such as a doctor, nurse, paramedic, technician, and the like. Support arm 426 includes an angled support pad 438 containing a pocket 440. Transdermal delivery device 420 includes a securing mechanism 442 provided on device 420 to attach device 420 to a mating feature 444 in angled support pad 438. Once device 420 is secured to support apparatus 418, a removable layer can be separated from support apparatus 418 to expose a drug container or reservoir 446, after which support apparatus 418 can be secured to a head such that drug container 446 is positioned against ABTT terminus 10.

FIG. 40 is a view of another passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 448. Device 448 includes a support 450 and a strap 452 configured to secure device support 450 to a patient or subject's head.

FIG. 41 is a view of another passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 474. Transdermal delivery device 474 is shown positioned on ABTT terminus 10. Device 474 includes a support 476 and a drug container or reservoir 478. Device 474 further includes an adhesive layer 480 that is configured to generate heat when a removable layer is separated from device 474. The benefit of heat generation in device 474 is that heat improves the permeability of skin 482 to the drug in drug container 478. FIG. 41 also shows the lack of fat and the thinnest skin in the body at ABTT terminus 10, and fat with thick skin 484 located in areas outside ABTT terminus 10. As has been explained herein, drugs that flow through the skin of ABTT terminus 10 flow into ABTT 10, and then into cavernous sinus 486. From cavernous sinus 486, drugs flow directly into the surrounding tissues of a brain 488, without the complexities of flowing through the digestive system and the circulatory system, including the liver and the kidneys. Accordingly, drugs that flow directly into ABTT 12 from all sources, especially ABTT terminus 10 and veins 14, 16, 18, 20, and 22, provide a greater effect on brain tissues than any other application of drugs to the human body, and consequently, fewer amounts of drugs and/or lower drug concentration than what is used in conventional patches, as described herein, need to be applied at these locations to be effective.

FIG. 42 shows yet another passive transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 490.

FIG. 52 is a transdermal delivery system in accordance with an exemplary embodiment, indicated generally at 592. System 592 includes at least one passive or active transdermal delivery device 594 that may be any of the passive transdermal delivery devices described herein, and a pair of warming and cooling gloves 596. Gloves 596 are connected to a controller 598, which can be configured to include an ON/OFF switch 600, a temperature controller 602, and a temperature display 604. System 592 provides an enhanced delivery of drugs to a subject or patient 606 by tricking the brain into functioning in a certain way. More specifically, system 592 operates by making the brain think that the ambient temperature is about to become hot by activating thermal receptors in the subject's hands by applying heat to gloves 596. The brain, sensing the heat in the hands, prepares for the apparent increase in temperature by causing cool blood to flow from one or more veins 14, 16, 18, or 20 into ABTT 12. This blood flow will cause drugs flowing through ABTT terminus 10 and any drugs flowing through veins 14, 16, 18, or 20 to flow into ABTT 12 at a faster rate than might normally occur in typical ambient and body temperatures. Indeed, the brain may be causing warm blood to flow outwardly through ABTT 12, which would render the application of drugs less effective. Gloves 596 are also capable of cooling the hands. If the face contains warm blood, the brain can still cause inward blood flow, accomplishing the same effect. In order to know how the brain is functioning with respect to facial blood flow, system 592 may be configured to include a plurality of temperature sensors positioned to measure ambient temperature, facial skin temperature, and temperature at an ABTT 10, which can be presented on temperature display 604, as well as devices that measure blood flow.

FIG. 53 is a view of an active transdermal delivery system in accordance with an exemplary embodiment of the present disclosure, indicated generally at 610. System 610 includes an active transdermal delivery device 612, one or more electric gloves 614, one or more electric boots 616, and a controller 618. Generally, device 612 is controllable to provide flow of a drug to a patient or subject while gloves 614 and boots 616 are heated or cooled to fool the brain into controlling blood flow from the face into ABTT 12. System 610 further includes a plurality of temperature sensors, such as temperature sensor 608 for measuring ambient temperature, and temperature sensors integral to gloves 614 and boots 616. Additional temperature sensor can be positioned to measure face and ABTT terminus temperature (not shown).

Device 612 includes a drug delivery interface 620 configured to deliver a drug to ABTT terminus 10. Drug delivery interface 620 is connected by a fluid delivery system 622 to a reservoir 624. Fluid delivery system 622 includes a variable or adjustable valve 626 and can include a pump 628. When commanded by controller 618, variable valve 626 can be opened to permit a drug to flow from reservoir 624 through fluid delivery system 622 to drug delivery interface 620. If needed to augment drug flow, controller 618 may also command a pump to move the drug through fluid delivery system 622 to drug delivery interface 620. Controller 618 can be configured to include a display 630 to provide a readout of temperature and other information, a temperature controller 632, a flow control 634, and an ON/OFF switch 636, along with other controls. As noted with the embodiment of FIG. 52, the brain may be tricked by heating or cooling thermal receptors in the hands or feet by heating of cooling gloves 614 and boots 616. The brain then causes blood flow, or increased blood flow, from the veins of the face into ABTT 12 in response to the thermal stimulation of the hands and feet, improving and controlling the delivery of drugs to the brain. It should be noted that excessive drug flow can also be controlled by reducing the blood flow to the brain by appropriate adjustment of glove 614 and boot 616 temperature.

FIG. 54 is a view of another active transdermal delivery system in accordance with an exemplary embodiment of the present disclosure, indicated generally at 638. System 638 includes a drug delivery interface 640 configured to include a permeable material 642. Drug delivery interface 640 is connected to a fluid reservoir 644 containing a drug 646. Interface 640 is connected to reservoir 644 by a fluid delivery system that can include one or more fluid passages 650 and a variable valve 652. Reservoir 644 is configured to be pressurized by an air delivery system 654 that can include an air supply valve 656 positioned between an air source 658 and fluid delivery system 648. When a drug needs to be delivered to drug delivery interface 640, variable valve 652 can be opened to start the flow of drug 646 from reservoir 644 into fluid delivery system 648, and then to drug delivery interface 640. If the flow of drug 646 to drug delivery interface 640 is inadequate, air supply valve 656 is opened to connect air source 658 to reservoir 644, forcing additional flow of drug 646 into fluid delivery system 648 to drug delivery interface 640. Air source 658 can be any of a plurality of sources of pressurized air, including nitrogen systems, filtered air pumps, and bottled air. In the embodiment of FIG. 54, air source 658 is configured as a balloon, which often is sufficient to provide enough pressure to provide sufficient supply of drug 646 to drug delivery interface 640.

Device 660 also includes a thermoelectric device 670 positioned transversely between drug container 664 and device support 662. When removable layer 668 is removed from device 660, as shown in FIG. 55 (FIG. 56 shows removable layer 668 in place), drug container 664 is exposed and ready for placement on ABTT terminus 10, secured by adhesive layer 668. Power is applied to thermoelectric device 670 through wires 672 to heat drug container 664 and the skin around ABTT terminus 10. By heating drug container 664, the drug contained therein becomes more energetic and more likely to permeate skin. Furthermore, the skin of ABTT terminus 10 also increases in permeability due to the heat, and drug flow through ABTT terminus 10 is thereby enhanced.

FIG. 57 is a view of a passive transdermal delivery module in accordance with an exemplary embodiment of the present disclosure, indicated generally at 674.

FIG. 61 is a view of a basic active transdermal delivery system in accordance with an exemplary embodiment of the present disclosure, indicated generally at 720. System 720 includes a drug delivery interface 722, a drug reservoir 724, and a controller 726. Drug delivery interface 722 includes an absorbent material 728 positioned in an annular thermoelectric device 730. Drug delivery device 722 is connected to reservoir 724 by a flexible arm or support 732, which is configured to support a fluid passage extending between reservoir 724 and absorbent material 728. Controller 726 is connected to thermoelectric device 730 by a wire or cable 734. Controller 726 is configured to connect and disconnect power to thermoelectric device 730, and to vary the amount of power to control temperature delivered to a subject or patient.

Controller 726 can further include a display to present the temperature of various locations, including ambient, facial skin, extremity (hands and feet), rectal, oral, axillary, ABTT terminus 10, and the like.

The goal of the flexible arm or support 732 is to permit adjusting the position of drug delivery interface 722 to match the location of ABTT terminus 10 as well as possible, and to maintain contact between absorbent material 728, or other drug delivery media, and ABTT terminus 10. FIG. 62 is a view of a drug delivery interface incorporating a spring to assist in accordance with an exemplary embodiment of the present disclosure, indicated generally at 736. Drug delivery interface includes a drug container or reservoir 738 positioned in an annular opening 740 of a thermoelectric device 742. Thermoelectric device 742 and drug container are secured to a support base 744 by a plurality of connectors 746 that slidingly interface with a plurality of slots 748. In the exemplary embodiment of FIG. 62, slots 748 are located on support base 744, and connectors 746 are fixedly attached at a peripheral location of thermoelectric device 742. A spring 750 is positioned between thermoelectric device 742 and support base 744. The function of spring 750 is to permit drug delivery interface 736 to be moved into contact with ABTT terminus 10, which then compresses spring 750, which is configured to maintain contact with ABTT terminus 10 in the event of limited movement of drug delivery interface 736. Drug delivery interface 736 further includes a flexible arm or support 752, which further includes an attachment arrangement 754 to permit secure attachment of drug delivery interface 736 to another device or apparatus, such as a separate support.

FIG. 63 is a view of an active transdermal delivery device configured to deliver two drugs, in accordance with an exemplary embodiment of the present disclosure, indicated generally at 758. It should be understood that FIG. 63 is configured as a block diagram, and certain features, such as drug containers, are positioned such that when device 758 is properly placed on the skin, the appropriate features are positioned in contact with the skin. The thermoelectric devices described in conjunction with device 758 need not be positioned in direct contact with the skin, but need to be positioned in a location that provides thermal communication with the skin.

Device 758 is configured to take advantage of change in skin permeability with temperature, and, in some cases, the increased transport of drugs with temperature. For most drugs, as shown in studies by Applicant, skin permeability increases with an increase in temperature, and decreases with a decrease in temperature. Accordingly, the flow of drugs through the skin may be halted by modifying skin permeability with temperature. In addition, for drugs where skin permeability increases with temperature, the mobility of the drug increases with temperature, further improving the flow of drugs through the skin of ABTT terminus 10 to reach ABTT 12.

Device 758 includes a support 760, on which are positioned or located a first drug container or reservoir 762 and a second drug container or reservoir 764, separated by a thermal insulator 766. Device 758 further includes a first thermoelectric device 768 positioned on an opposite side of first drug container 762 from second drug container 764, and a second thermoelectric device 770 positioned on an opposite side of second drug container 764 from first drug container 762. In the exemplary embodiment of FIG. 63, a power supply 772 is also positioned on support 760 and connected to various elements of device 758 to provide power for operation. A first temperature sensor 774 and a second temperature sensor 776 are positioned in proximity to first drug container 762 and second drug container 764, respectively. First temperature sensor 774 and second temperature sensor 776 enable refined control of the temperature of first drug container 762 and second drug container 764, and, consequently, control of the delivery of drugs through the skin. For example, by decreasing the temperature of first thermoelectric device 768 by an amount equal to at least one degree Celsius below the initial or nominal skin temperature, permeability of the skin to most drugs drops to approximately zero, effectively stopping or shutting off the flow of drugs through the skin. Conversely, increasing the temperature of the skin a degree above the initial or nominal skin temperature increases skin permeability by about 30% for most of the drugs tested, and described herein. Thus, controlling the temperature of a thermoelectric device positioned adjacent to a drug container in contact with the skin controls drug flow through the skin. Thus, it is an object of the disclosure to provide a device that controls flow of drugs through the skin using a combination of warming and cooling.

Device 758 can further include a transmitter, receiver, or transceiver 778 configured for communication with a separate electronic device 780, such as a cell phone, laptop, tablet, watch, etc. Such communication with separate electronic device 780 permits control of device 758 and, when device 758 is provided with sensors, monitoring of device 758.

Device 782 includes a support 784 on which is positioned a first drug container or reservoir 786 and a second drug container or reservoir 788, separate by a thermal insulator 790. A first temperature sensor 792 may be positioned proximate or over first drug container 786 and a second temperature sensor 794 may be positioned proximate or over second drug container 788 to measure, indirectly, the temperature of the skin over which first drug container 786 and second drug container 788 are positioned. Device 782 further includes at least one first thermoelectric device 796, and may include a plurality of first thermoelectric devices 796 positioned about a periphery of first drug container 786, and at least one second thermoelectric device 798, and may include a plurality of second thermoelectric devices 798 positioned about a periphery of second drug container 788. First thermoelectric device(s) 796 and second thermoelectric device(s) 798 are positioned on a periphery that is away from the portion of the periphery that is along thermal insulator 790. Device 782 is further configured to include a power supply 800 for providing power to the various elements positioned on device support 784. Device 782 further includes a controller 802 configured to operate various elements of device 782, and a transceiver, transmitter, or receiver 804 configured to communicate with a separate electronic device 806, which may be a cell phone, tablet, laptop, watch, etc.

FIG. 65 is a first graph demonstrating controlled drug flow in accordance with an exemplary embodiment of the present disclosure. As described herein, by controlling the temperature of the skin adjacent to an absorbent material, drug container, or drug reservoir, the flow of a drug through the skin can be controlled. FIG. 65 shows a stylized graph of drug flow from a conventional transdermal patch attached to the skin in comparison to one of the infinite patterns possible with an actively controlled transdermal device disclosed herein. A conventional device begins to deliver a drug to the skin at T0, building to a peak flow rate at T1. The drug then flows until drug depletion nears, at time T3, eventually falling to zero at time T4. In contrast, an actively controlled transdermal device generates transdermal drug delivery faster than a conventional device, shown by the steep slope at the beginning of the curve just after T0, which represents controlled fluid flow through the skin by increasing temperature with the thermal devices of the disclosure. At time T2, the temperature of the skin is reduced to decrease drug flow until a new steady state is reached at time T3. The delivery rate is sustained from time T3 to time T4, at which time drug delivery is reduced to zero, again by temperature control.

FIG. 66 is a second graph demonstrating controlled drug flow in accordance with an exemplary embodiment of the present disclosure. From time T0 to T1, skin temperature is held below nominal, and a drug delivery rate is minimal or zero. At time T1, skin temperature is increased to raise the drug delivery rate rapidly to a peak at T2 to provide an initial flood of drugs, followed by a decrease in skin temperature from time T2 to time T3, which reduces the flow of drugs through the skin. From time T3 onward, the flow rate of drugs through the skin is maintained at a steady state, sometimes supported by a reservoir, which may be integral or separate.

FIG. 67 is a third graph demonstrating controlled drug flow in accordance with an exemplary embodiment of the present disclosure. In FIG. 67, the temperature is varied to turn drug flow off and on, increasing the rate of drug flow during each subsequent activation of drug flow.

FIG. 68 is a fourth graph demonstrating controlled drug flow in accordance with an exemplary embodiment of the present disclosure. In FIG. 68, the rate of drug flow is stepped up over time, until drug flow is turned off at time T8 by reducing skin temperature below nominal or normal.

FIG. 69 is a fifth graph demonstrating controlled drug flow in accordance with an exemplary embodiment of the present disclosure. The rate of drug flow is opposite that shown in FIG. 68, beginning at a relatively high level and decreasing in steps over time until the drug flow is eventually reduced to zero by controlling the temperature of the skin.

FIG. 70 is a sixth graph demonstrating controlled drug flow in accordance with an exemplary embodiment of the present disclosure. In FIG. 70, drug flow is turned on and off with time, with the maximum flow rate decreased each time.

Device 928 further includes a second thermoelectric device 942 positioned alongside, adjacent to, or next to second drug container 938, and a third thermoelectric device 944 positioned alongside, adjacent to, or next to third drug container 940. Second thermoelectric device 942 is positioned to control the flow of drugs from second drug container 938 into second ABTT terminus 10, and third thermoelectric device 944 is positioned to control the flow of drugs from third drug container 940 into second ABTT terminus 10. Thus, a single active transdermal delivery device, such as device 928, can be configured to deliver a plurality of different drugs to a patient or subject 948. Device 928 can further include a second temperature sensor 950 and a third temperature sensor 952 positioned adjacent to second drug container 938 and third drug container 940, respectively, to monitor the temperature of each drug container.

Device support 930 further includes a first clip 954 and a second clip 956 connected to each other by a bridge 958. Bridge 958 can be configured to include a plurality of electronic elements, such as a controller 960; a transceiver, transmitter, or receiver 962 configured to communicate with a separate electronic device 964, such as a laptop, tablet, cell phone, watch, etc.; and a power supply 966.

FIG. 78 is a cross-sectional view of an active transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 968. Device 968 includes a housing assembly 970. Housing assembly 970 includes a side wall 972, which can be configured as an annulus, an upper cover 974, and a lower housing member 976. Lower housing member 976 includes a plurality of openings 978 formed therein. Housing assembly 970 forms an internal cavity, volume, or chamber 980, in which are positioned an actuation device 982 and an absorbent material 984. Absorbent material 984 is configured to extend into plurality of openings 978 such that a bottom surface 988 of absorbent material 984 is approximately parallel to a bottom surface 986 of lower housing member 976.

A removable or peelable layer 994 covers at least a portion of bottom surface 986 of lower housing member 976 and bottom surface 988 of absorbent material 984. Separation of removable layer 994 exposes bottom surface 988 so that bottom surface 988 can be accessible for contact with ABTT terminus 10.

Device 968 includes a movable fluid passage 990 that extends through an opening 992 formed in upper cover 974. As will be seen, fluid passage 990 is secured to an element of actuation device 982 and is movable by the operation of actuation device 982. A seal 1002 is positioned on lower housing member 976 so that when actuation device 982 operates, movable fluid passage 990 contacts seal 1002 and prevents the movement of fluid from movable fluid passage 990 into absorbent material 984. When actuation device 982 is released, fluid, e.g., a drug, is able to flow from movable fluid passage 990 into absorbent material 984.

Actuation device 982 includes a coil 996 and a movable plate 998 biased toward a top of internal cavity 980 by one or more bias springs 1000. When actuation device 982 is operated, such as by an external controller 1004 by way of a wireless connection or a wire or cable 1006, movable plate 998 is pulled toward a top surface 1008 of induction coil 996, which pulls fluid passage 990 downward toward seal 1002. Fluid passage 990 makes contact with seal 1002 just before movable plate 998 makes contact with induction coil 996, preventing a flow of fluid 1012, e.g., a drug, from a reservoir 1010 connected to movable fluid passage 990, blocking a flow of fluid 1012 to absorbent material 984. When actuation device 982 is released, movable plate 998 is released, moving an end of fluid passage 990 away from seal 1002, permitting fluid 1012 to flow from reservoir 1010 through fluid passage 990 into absorbent material. Thus, actuation device 982 controls the flow of fluid 1012 into absorbent material 984, and then into an associated ABTT terminus 10 and/or associated veins 14, 16, 18, 20, and 22. FIG. 79 is a view of an active transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1014. Device 1014 includes a support 1016 in which is positioned a first drug container 1018, and an annular thermoelectric device 1020 positioned on device support 1016. A second drug container 1022 is positioned in a volume 1024 formed within a central portion of annular thermoelectric device 1020. To protect first drug container 1018 and second drug container 1022, device 1014 includes a removable or peelable layer (not shown) configured to cover at least first drug container 1018 and a cover layer 1026 configured to cover at least second drug container 1022.

When the removable layer is separated from device 1014, exposing first drug container 1018, and device 1014 is place on ABTT terminus 10, the drugs in first drug container 1018, which are configured with a higher skin permeability than the drugs in second drug container 1022, provide an immediate release of drugs to ABTT terminus 10. The drugs in second drug container 1022 are activated by heat from thermoelectric device 1020, powered by a controller 1028 connected to thermoelectric device 1020 by, for example, wires, or a cable 1030. Controller 1028 may be co-located with device 1014 or may be separately positioned.

Device 1014 is configured to provide a first release of drugs from first drug container 1018, typically at a first flow rate, and then to provide a second release of drugs from second drug container 1022, often at a lower flow rate that may be sustained for a period that is longer than the period for delivery of drugs from first drug container 1018. However, second drug container 1022 can be configured to deliver drugs at varying flow rates with the presence of thermoelectric device 1020, and can also be configured to deliver a second drug that is different from a first drug positioned in first drug container 1018. It should be understood that first drug container 1018 can contain a skin permeation enhancer that increases skin permeability, and second drug container 1022 contains a drug.

FIGS. 80-82 are views of a portion of a transdermal delivery device, which may be passive or active, incorporating a replaceable drug reservoir, in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1032. Device 1032 includes a support frame 1034, which can be, for example, an eyeglass frame. Support frame 1034 includes nose pads 1036 to provide at least partial support for support frame 1034 on a subject or user's face. Support frame 1034 also includes a longitudinally extending cavity or recess 1036 configured to receive a separate reservoir 1038. Support frame 1034 further includes a transdermal drug delivery module 1040 positioned in a location such that when support frame 1034 is located on the subject or user's head, transdermal drug delivery module 1040 is configurable to be positioned on the subject or user's ABTT terminus 10. Though not shown, it should be understood that device 1032 is likely to include a second drug delivery module 1040 for the subject's other ABTT terminus 10.

Transdermal drug delivery module 1040 includes a reservoir cavity 1042 configured to contain a drug 1044, with reservoir cavity 1042 covered or enclosed by an absorbent material 1046 that permits drug 1044 flow therethrough when in contact with an ABTT terminus 10 for transdermal delivery of drug 1044 to the subject or patient. It should be understood that absorbent material 1046 can fill reservoir cavity 1042 in its entirety. Thus, liquid separate from absorbent material 1046 may not be present in reservoir cavity 1042, and in this alternative embodiment (not shown) the liquid is contained and stopped at the level of fluid passage 1052, thereby allowing better control of the delivery of drug 1044 to absorbent material 1046. Transdermal drug delivery module 1040 is connected or attached to support frame 1034 by a flexible arm 1048. Reservoir cavity 1042 is connected to separate reservoir 1038 by a first fluid passage 1050 formed in support frame 1034, which is fluidly connected to a second fluid passage 1052 that extends through flexible arm 1048 to connect with reservoir cavity 1042. Thus, when separate reservoir 1038 is positioned in support frame 1034, device 1032 is configured to provide an extended period of drug 1044 delivery to a patient or subject.

Separate reservoir 1038 may be fabricated from any suitable material that is inert with respect to drug 1044, which can include some types of glass and plastic. Reservoir 1038 is covered at one end by a membrane 1054 that seals drug 1044 in reservoir 1038 until reservoir 1038 is installed in support frame 1034. When reservoir 1038 is inserted into longitudinally extending cavity 1036, a penetration or piercing device, apparatus, or mechanism 1056 punctures membrane 1054, permitting drug 1044 to flow into first fluid passage 1050. Membrane 1054 extending about an end surface of separate reservoir 1038 serves as a seal to prevent leakage when separate reservoir 1038 is positioned in support frame 1034. Alternatively, membrane 1054 can be removed or punctured prior to installation in support frame 1034.

FIG. 83 is a perspective view of a separate drug reservoir in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1058. While separate reservoir 1038 shown in FIGS. 80 and 81 is beneficial in many gravity fed systems, providing an active pump in association with a separate reservoir can be beneficial in some transdermal delivery device configurations. Separate drug reservoir 1058 includes a reservoir body 1060 that includes a cavity or volume for storage of a drug. An end cap or cover 1062 encloses the cavity or volume of reservoir 1058. In the exemplary embodiment of FIG. 83, end cap or cover 1062 includes a pump cap 1064 containing a small fluid pump 1066 that may be formed, for example, by a MEMS process. A driver cap 1068 configured to include a pump drive 1070 is configured to be positioned on pump cap 1064. Pump drive 1070 is configured to be power by an external power supply 1072 connected by wires or a cable 1074 driver cap 1068 and then to pump drive 1070. Driver cap 1068 further includes a fluid passage 1076 that connects fluid pump 1066 to, for example, a transdermal drug delivery module.

FIG. 84 is a perspective view of a mask incorporating an active transdermal delivery system in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1078. Mask 1078 includes a mask body 1080 configured to include an active transdermal drug delivery system 1082, and a passive transdermal drug delivery device 1084.

Passive transdermal drug delivery device 1084 includes a first drug container, which may be similar to drug container 466 shown in FIG. 40, positioned on a first angular extension 1086, and a second drug container, which may be similar to drug container 468 shown in FIG. 40, positioned on a second angular extension 1088. The first drug container and the second drug container in this embodiment are configured to contact at least a portion of angular veins 20, and may extend to contact at least a portion of facial veins 22. First angular extension 1086 and second angular extension 1088 are preferably made with a flexible or conformable material for close apposition to the skin surface overlying the veins. It should be understood that an adhesive surface may be included in first angular extension 1086 and second angular extension 1088 or on the skin surface of the first drug container and the second drug container.

Active transdermal delivery device 1082 includes a plurality of drug reservoirs 1090 configured to mate with appropriately configured receptacles 1092 in mask body 1080. Drugs from any one drug reservoir 1090 may be released upon command, such as through a control device 1094 connected to mask 1078 wirelessly or by wires or a cable 1096.

FIG. 71 is a seventh graph demonstrating controlled drug flow in device 1082 in accordance with an exemplary embodiment of the present disclosure. Because device 1082 can be configured to include a plurality of different drugs, and delivery of each drug to ABTT terminus 10 can be controlled, an infinite number of delivery times and quantities are possible. For example, FIG. 71 plots the flow of three drugs A, B, and C during a twenty-four hour period. Drug A is provided during the first six hours, drug B is provided as shown in two intervals that do not overlap with the interval of drug A, and drug C is provided throughout the twenty-four hour interval.

FIG. 85 is a perspective view of a portion of the active transdermal delivery system of FIG. 84, showing drug reservoirs 1090 removed from mask body 1080. FIG. 86 is a cross-sectional view of the portion of FIG. 85 along the lines 86-86. As shown in FIG. 86, mask 1078 further includes a plurality of penetrating, puncturing, or piercing devices, apparatuses, or mechanisms 1098-1104, which are configured to pierce or penetrate a membrane 1106 configured as a part of each drug reservoir 1090 to seal a drug 1108 in reservoir 1090. Mask 1078 further includes a plurality of flow control valves 1110 configured to control the flow of drugs from drug reservoirs 1090 into a fluid passage 1112 formed in mask body 1080. Once in fluid passage 1112, drugs flow into a flexible arm 1114 configured to extend from mask body 1080 and terminating in a drug delivery interface 1116. In the exemplary embodiment of FIGS. 84 and 86, flow control valves 1110 are electrically operated by way of control device 1094. In other embodiments, flow control valves 1110 may be operated mechanically, electrically under the control of a timer, by an external program stored, for example, in a cell phone, and in other ways.

FIG. 87 is a perspective view of a puncture, piercing, or penetrating device compatible with the configuration of FIG. 86, in accordance with an exemplary embodiment of the present disclosure and indicated generally at 1118. Device 1118 is configured with a penetrating, piercing, or puncturing first end 1120 configured to enter and extend through membrane 1106 when a reservoir, such as reservoir 1090, is inserted into a corresponding receptacle 1092. Device 1118 includes a first opening 1122 and a second opening 1124 fluidly connected to first opening 1122. In operation, a drug flows into first opening 1122, through a passage (not shown) internal to device 1118, and out from second opening 1124, entering flow control valve 1110.

FIG. 88 is a perspective view of a puncture, piercing, or penetrating device compatible with the configuration of FIG. 86, in accordance with an exemplary embodiment of the present disclosure and indicated generally at 1126. Device 1126 is configured with a penetrating, piercing, or puncturing first end 1128 configured to enter and extend through membrane 1106 when a reservoir, such as reservoir 1090, is inserted into a corresponding receptacle 1092. Device 1126 includes a longitudinally extending groove 1130. In operation, a drug flows into longitudinally extending groove 1130 at first end 1128, and along groove 1130 into flow control valve 1110.

FIG. 89 is a view of an active transdermal delivery system in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1132. System 1132 is configured to include a capability to provide a drug when authorized by an authorized practitioner, such as a doctor. System 1132 includes a transdermal drug delivery module 1134 fluidly connected to a drug reservoir 1136. An electrically actuated valve 1138 is positioned along a fluid passage 1140 extending between drug delivery module 1134 and drug reservoir 1136. Valve 1138 is configured to be opened and closed in response to a command from a controller 1142 configured as a part of system 1132. In the embodiment of FIG. 89, controller 1142 can be operated from a control panel 1144, which may be configured as a part of controller 1142, or wirelessly by a separate electronic device 1146, such as a tablet, cell phone, laptop, and the like. System 1132 further includes a monitoring device 1148 configured to read signals from ABTT terminus 10. Monitoring device 1148 can be, for example, an infrared sensor or a temperature sensor configured to read the output from ABTT terminus 10. Output signals corresponding to the signals output from ABTT terminus 10 are provided to controller 1142. Control panel 1144 further includes an indicator light 1150. As will be seen, system 1132 provides benefits in remote and voluntary treatment of patients.

FIG. 90 is a drug delivery process flow of the system of FIG. 89 in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1152. Process 1152 begins with a start process 1154. In start process 1154, system 1132 is powered, drug reservoir 1136 is filled with a drug and installed in system 1132, transdermal delivery module 1134 is positioned on a patient or subject's first ABTT terminus 10, and monitoring device 1148 is positioned on a patient or subject's second ABTT terminus 10. Once start process 1154 is complete, control passes from start process 1154 to a request authorization process 1156.

In request authorization process 1156, a patient, subject, or designated person requests authorization for the drug in reservoir 1136 to be provided to the patient or subject. Such request may be by phone, internet, in person, etc. Once the request is submitted, control passes from request authorization process 1156 to a practitioner authorization process 1158.

In practitioner authorization process 1158, a doctor, nurse, physician's assistant, or other legally authorized person transmits authorization for a particular patient to system 1132. Such transmission may be wireless, such as by separate electronic device 1146, by entry directly into control panel 1144, or by other apparatus. Once a legally authorized person has approved the drug use, control passes from practitioner authorization process 1158 to an indicator process 1160, where an indicator, such as indicator 1150 on control panel 1144, indicates that drug authorization has been received. Control then passes from indicator process 1160 to a patient authorization process 1162.

In patient authorization process 1162, a patient determines the need for the drug, and activates delivery by way of control panel 1144, wirelessly, or through other apparatus. Control then passes from patient authorization process 1162 to a patient monitoring process 1164.

In patient monitoring process 1164, system 1132 receives data from a monitoring device, such as a blood pressure monitor, a heart rate monitor, an oximeter, an electrocardiogram (EKG), an electroencephalogram (EEG), and the like. In the exemplary embodiment of FIG. 89, the monitoring device is ABTT monitoring device 1148. Control then passes from patient monitoring process 1164 to a monitor data analysis process 1166. In monitor data analysis process 1166, system 1152 determines, in view of signals from a monitor, such as ABTT monitoring device 1148, whether the patient is the correct patient by analysis of the thermal signature of the patient, and whether the patient requires the drug. Control then passes from monitor data analysis process 1166 to a drug required decision process 1168.

In drug required decision process 1168, system 1132 determines whether the authorized drug is required, in view of the analysis conducted in monitor data analysis process 1166. If the drug is not required, control passes from drug required decision process 1168 to patient monitoring process 1164, and process 1152 continues as previously described. If the drug is required, control passes from drug required decision process 1168 to a drug delivery process 1170.

In drug delivery process 1170, valve 1138 is opened and the drug in reservoir 1136 is delivered to ABTT terminus 10 by transdermal delivery module 1134. Control then passes to an additional drug available process 1172.

In additional drug available process 1172, system 1132 determines whether an additional dosage of the drug is available, which can be accomplished by determining the amount originally provided in reservoir 1136, less delivered amounts, by visual sensors, and the like. If an additional dose of drug is available, control passes from additional drug available process 1172 to a dose authorized process 1174.

In dose authorized process 1174, process 1152 determines whether an additional dose has been authorized. If an additional dose has been authorized, control passes from dose authorized process 1174 to patient monitoring process 1164, and process 1152 continues as previously described. If an additional dose has not been authorized, control passes to a practitioner authorization required process 1176, where an indicator, such as indicator 1150 on control panel 1144, indicates the need for a legally authorized practitioner, such as a doctor, physician's assistant, nurse, and the like, as permitted by law, to authorize another dose of the drug in reservoir 1136. Control then passes from practitioner authorization required process 1176 to an end process 1180, which terminates process 1152.

Returning to additional drug available process 1172, if an additional dosage is not available, control passes from process 1172 to a drug depleted process 1178, in which an indicator, such as indicator 1150 on control panel 1144, indicates the need to replenish the drug in reservoir 1136. Control then passes to end process 1180, which terminates process 1152.

It should be apparent that process 1152 is beneficial in that it allows a patient to have ready access to drugs when authorized by a practitioner, without the need to return to a pharmacy constantly. Furthermore, by monitoring a patient through ABTT terminus 10, a practitioner is able to verify a patient's condition prior to authorizing delivery of the drug in reservoir 1136, increasing the efficiency of medical care, and reducing costs. It should be understood that other medical monitoring devices, such as blood pressure monitoring, heart rate monitoring, oximetry, Electrocardiogram (EKG), electroencephalogram (EEG), and the like, can provide a feedback loop to system 1132. In this feedback loop embodiment, the signal from other medical devices may control automatically, by increasing drug flow or decreasing drug flow, the drugs being administered transdermally by system 1132.

FIG. 91 is another drug delivery process flow of the system of FIG. 89 in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1182. Process 1182 begins with a start process 1184. In start process 1184, system 1132 is powered, drug reservoir 1136 is filled with a drug and installed in system 1132, transdermal delivery module 1134 is positioned on a patient or subject's first ABTT terminus 10, and monitoring device 1148 is positioned on a patient or subject's second ABTT terminus 10. Once start process 1184 is complete, control passes from start process 1184 to a request authorization process 1186.

In request authorization process 1186, a patient, subject, or designated person requests authorization for the drug in reservoir 1136 to be provided to the patient or subject. Such request may be by phone, internet, in person, etc. Once the request is submitted, control passes from request authorization process 1186 to a practitioner authorization process 1188.

In practitioner authorization process 1188, a doctor, nurse, physician's assistant, or other legally authorized person transmits authorization for a particular patient to system 1132. Such transmission may be wireless, such as by a separate electronic device 1146, such as, for example, a cell phone, by entry directly into control panel 1144, or by other apparatus. Once a legally authorized person has approved the drug use, control passes from practitioner authorization process 1188 to an indicator process 1190, where an indicator, such as indicator 1150 on control panel 1144, indicates that drug authorization has been received. Control then passes from indicator process 1190 to a patient authorization process 1192.

In patient authorization process 1192, a patient determines the need for the drug, and activates delivery by way of control panel 1144, wirelessly, or through other apparatus. Control then passes from patient authorization process 1192 to an additional dosage authorized process 1194, where process 1182 determines whether the practitioner has authorized an additional dosage. If an additional dosage has been authorized, control passes from additional dosage authorized process 1194 to a predetermined interval process 1198. If an additional dosage is not authorized, control passes from additional dosage authorized process 1194 to an end process 1196, which terminates process 1182.

In predetermined interval process 1198, system 1132 measures a predetermined passage of time such as, for example, four, six, eight, twelve, or twenty-four hours. If the predetermined interval has yet to be reached, process 1198 continues in a loop until the predetermined time interval is reached, after which control passes from predetermined interval process 1198 to an automatic drug delivery authorization process 1200.

In automatic drug delivery authorization process 1200, process 1182 determines whether the patient has authorized automatic delivery of the drug in reservoir 1136. If automatic delivery has been authorized, control passes to a drug delivery process 1202, where the drug is delivered. Control then passes from drug delivery process 1202 to additional dosage process 1194, and process 1182 continues as previously described. If automatic delivery has not been authorized, control passes from automatic drug delivery authorization process 1200 to patient authorization process 1192, and process 1182 continues as previously described herein.

A benefit to process 1182 is that automatic delivery of drugs to ABTT terminus 10 can occur without a need for a patient to remember that it is time for another dosage. Further, delivery can, as with process 1152, be remotely authorized by a legally authorized practitioner, providing a safe, fast, efficient, process for authorizing and delivering drugs to a patient.

FIG. 92 is another transdermal delivery system in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1204. System 1204 includes a support device 1206 on which is positioned a transdermal drug delivery module 1208 and a plurality of accelerometers or other motion detection devices 1210. Transdermal drug delivery module 1208 includes one or more drug containers 1212 configured to deliver a drug to a respective ABTT terminus 10. Drug containers 1212 are connected to a reservoir and flow control apparatus 1214 configured to supply a drug to drug containers 1212 by way of fluid passages 1216, when commanded by a controller 1218 positioned on support device 1206. Controller 1218 may include a transceiver, transmitter, or receiver (not shown), or such may be provided separately on support device 1206, which is configured to communicate with a separate electronic device 1220 for monitoring of a patient 1222 and control of system 1204. Controller 1218 further includes an integral timer or clock that can be configured to include a timer or timing function, including wake alarms. Timer-related alarms in controller 1218 can be set by way of, for example, separate electronic device 1220 when separate electronic device 1220 is configured with the appropriate interface software. System 1204 may also include a wrist band 1224 that includes one or more motion detection devices 1210. Wrist band 1224 may communicate with controller 1218 by a cable or wire (not shown) or wirelessly.

System 1204 is configured to provide one or more drugs to patient 1222 when needed for a condition that generates certain characteristic motions that can be detected by motion detection devices 1210. Such characteristic motions can include semi-wakefulness for sleep disorders and seizures. Wrist band 1222 can be beneficial for some conditions because hand movements are sometimes an indication of an imminent condition.

FIG. 93 is a sleep treatment process of the system of FIG. 92, indicated generally at 1226. Process 1226 begins with a start process 1228, where power may be provided to system 1204, which can be properly positioned on patient 1222, drugs can be provided to reservoir and flow control apparatus 1214, and other actions necessary to prepare system 1204 and process 1226 for operation. Once start process 1228 is complete, control passes from start process 1228 to a receive motion sensor data process 1230.

In receive motion sensor data process 1230, controller 1218 receives signals from motion detection devices 1210. Control then passes from receive motion sensor data process 1230 to an analyze data process 1232. After analysis of motion sensor data, control passes to a semi-awake state decision process 1234, where process 1226 determines whether the signals provided by motion detection devices 1210 is indicative of a semi-awake state that is likely to lead to an awakened state. If a semi-awake state is not indicated, control passes from semi-awake state decision process 1234 to a predetermined wake time decision process 1236.

In predetermined wake time decision process 1236, system 1204 determines whether a predetermined wake time has been reached. The predetermined wake time can be set, for example, by way of separate electronic device 1220, using a timer or clock internal to controller 1218. In order to decrease the effect of a drug after awakening, the predetermined wake time can be a time after which no drugs are provided, even if a semi-awake state is reached. Thus, if a patient or subject plans to awaken at, for example, 6 AM, the predetermined “wake time” can be set for 4 AM, and no drugs will be administered after that time. Thus, the predetermined “wake time” can be consider a time at which the administration of drugs is stopped. If such a time has been reached, then control passes from predetermined wake time decision process 1236 to an end process 1238, where process 1226 terminates and patient 1222 is permitted to awaken. If the predetermined wake time has not been reached, control passes from predetermined wake time decision process 1236 to receive motion sensor data process 1230, and process 1226 continues as previously described herein.

Returning to semi-awake state decision process 1234, if a semi-awake condition is detected that is likely to lead to awakening, control passes from semi-awake state decision process 1234 to a condition decision process 1240, where the condition of patient 1222 is determined from at least motion detection sensors 1210. If an abnormal condition is indicated, control passes from condition decision process 1240 to an alarm process 1244, where one or more alarms are actuated, which can include an alarm to separate electronic device 1220. Control then moves from alarm process 1244 to end process 1238, where process 1226 terminates.

Returning to condition decision process 1240, if an abnormal condition is not detected, control passes from condition decision process 1240 to a sleep compound delivery process 1242, where a drug is delivered by reservoir and flow control apparatus 1214 to drug containers 1212 by way of fluid passages 1216, which should return patient 1222 to a condition of sleep. Control then passes from sleep compound delivery process 1242 to receive motion sensor data process 1230, where process 1226 continues as previously described herein.

FIG. 100 is a view of a tear diagnostic system in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1340. Certain drugs administered through ABTT terminus 10 and the retroauricular vein can be detected through tears in the eye. Thus, closed loop feedback system 1340 can be configured with a detector 1342 positioned, for example, on a contact lens 1344 that is then positioned on an eye 1346. Detector 1342 detects a level of a chemical or drug in eye 1346, and transmits that information wirelessly to an active transdermal drug delivery device or module 1348, which then adjusts the rate of drug flow through ABTT terminus 10 accordingly.

FIG. 101 is a view of another tear diagnostic system in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1350. System 1348 includes a detector 1352 positioned, for example, on a contact lens 1354 that is then positioned on an eye 1356. Detector 1352 detects a level of a chemical or drug in eye 1356, and transmits that information wirelessly to an active transdermal drug delivery device or module 1358 positioned on an eyeglass frame 1360, which then adjusts the rate of drug flow through ABTT terminus 10 accordingly. It should be understood that module 1358 can be positioned in any other support located in other parts of the body, and in other devices, such as the various embodiments described herein as clips, patches, masks, head gear, and the like.

FIG. 102 is a view of another active transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1362. Device 1362 is configured to include a support structure 1364, and a head support apparatus 1366.

Support structure 1364 includes a drug container 1368 positioned on, over, or adjacent the skin of ABTT terminus 10, at least one drug container 1370 positioned on, over, or adjacent the skin over superior palpebral vein 16, and at least one drug container 1372 positioned on, over, or adjacent the skin over frontal vein 20 and, in an alternative embodiment, over facial vein 22. It should be understood that drug containers 1368, 1370, and 1372 can be configured to include a same drug or a plurality of drugs. Support structure 1364 further includes a plurality of thermoelectric devices 1374 positioned in along support structure 1364. As described herein, by heating or cooling the skin, drug flow into associated veins is moderated or modified because the permeability of skin is related to temperature, and thermoelectric devices 1374 can both heat and cool. However, it should be understood that other temperature modification devices can be used in place of thermoelectric devices 1374, such as resistive heaters. Support structure 1364 can also be configured to include at least one temperature sensor 1376 to measure the temperature of support structure 1364, the temperature of one or more drug containers, or the temperature of the skin.

FIG. 103 is a view of a face showing locations for application of passive or active transdermal delivery devices, in accordance with an exemplary embodiment of the present disclosure. As described herein, passive and active devices can be positioned in a nearly infinite number of locations and combination of locations. However, it should be understood that the present disclosure also includes placement of passive and active transdermal devices on one or more veins or locations that feed, provide, direct, or guide blood to ABTT 12. For example, and as shown in FIG. 103, a passive or active transdermal delivery device 1388 can be positioned along either frontal vein 14, supraorbital vein 18, or both, a passive or active transdermal delivery device 1388 can be positioned along superior palpebral vein 16, and a passive or active transdermal delivery device can be positioned along angular vein 20 or frontal vein 22, without placement of a transdermal delivery device over ABTT terminus 10. The benefit to such placement is naturally modifying the rate of drug delivery to the brain rather than doing so with permeability modification apparatus or chemicals.

FIG. 104 is a view of a face showing additional locations available for placement of an active or a passive transdermal delivery device, in accordance with an exemplary embodiment of the present disclosure. A face 1394 shows placement of a passive or active transdermal delivery device 1396 on a roof of an orbit 1398, which may also be described as being under the eyebrow, or under the ridge of the brow. Face 1394 also shows placement of a passive or active transdermal delivery device 1400 on a side of nose 1402.

Active embodiments of the present disclosure describe heating or cooling of portions of faces for transdermal delivery. These embodiments include thermoelectric devices, chemical heating and cooling, and resistive heating. FIG. 105 shows a schematic view of an active transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1404. Device 1404 includes a drug container 1406 surrounded by a resistive heater 1408. Resistive heater 1408 is connected to a controller or power supply 1410 by a wire or cable 1412. Generally, thermoelectric devices provide the most capability given that they can heat or cool and are relatively accurate. Resistive devices are capable of heating only, and controlling such devices as precisely as thermoelectric devices typically requires more complex electronics than is necessary for thermoelectric devices. However, any heating or heating and cooling device can be used with the active devices disclosed herein as long as such devices can provide localized heating and cooling needed to control drug permeation through the skin.

One experimental technique used by Applicant to verify the efficacy of the systems, apparatuses, devices, processes, and methods disclosed herein was to compare absorption of a chemical into the blood stream. The chosen chemical was caffeine, and a comparison was made between distribution of caffeine in the body from a 15 mm by 15 mm patch placed on ABTT terminus 10 and a 15 mm by 15 mm patch placed on an upper arm. Caffeine concentration was measured in the same location on the body. As shown in FIG. 106, curve 1414 shows caffeine concentration with time for a caffeine patch positioned on the upper arm, and curve 1416 shows caffeine concentration with time for a caffeine patch positioned on ABTT terminus 10. As is evident from FIG. 106, the peak concentration of caffeine from the patch placed on the arm occurred five hours after placement of the patch, which peak concentration from the patch placed on ABTT terminus 10 was about 30 minutes after placement of the patch. Furthermore, peak concentration from placement of the patch on ABTT terminus 10 was more than twice as high as peak concentration from placement of the patch on the upper arm. Other compounds tested show similar results. Thus, the systems, apparatuses, devices, processes, and methods of the present disclosure, in addition to being novel, are significantly more effective than conventional application of transdermal patches. In addition, it should be noted that use of a known patch would be disadvantageous if applied to ABTT terminus 10, because a lesser quantity of a drug is required to achieve the same results. In fact, a conventional patch could prove to be dangerous if applied to ABTT terminus 10 due to the presence of a much higher quantity of drug than is required in combination with the high permeability of ABBT terminus 10, and the direct connection between ABTT terminus 10 and the brain. In order to achieve the same effect at ABTT terminus 10 as application of a conventional patch in a conventional application, only about ⅔ the quantity of a drug is required for the same effect at ABTT terminus 10.

FIG. 107 is a perspective view of another transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1418. Device 1418 is configured as an eyeglass frame 1420.

Wings 1438 are connected by a transversely extending bridge 1442, including a cover 1444. Cover 1444 is configured to be an area for printing, and indeed, the entire outer portion of device 1436, can be configured to provide a surface for writing or printing. By providing an area for writing, the drug or drugs included in device 1436 can be written or printed thereon, making such readily visible to an observer of device 1436. Alternatively, cover 1444 can include pre-printed information, such as the types and dosage of included drugs, along with permeation enhancers, if any. Furthermore, cover 1444 can include an advertisement for a product, for device 1436, artistic expression, etc. Thus, cover 1444 is a highly functional feature of device 1436.

FIG. 109 is a view of a transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1448. Device 1448 is configured to include a support 1450, which is configured to include a removable and replaceable drug container or patch 1452 and a plurality of electronics. The plurality of electronics can include a power supply 1454, a controller 1456, and a transceiver, transmitter, or receiver 1458, configured to communicate with a separate electronic device 1460, such as a cell phone, laptop, tablet, etc., which can also be configured to communicate with yet another separate electronic device 1462, such as a cell phone, table, laptop, etc. Support 1450 can also be configured with a permeability modification device or apparatus, such as a thermoelectric device 1464.

FIG. 110 is a view of a transdermal delivery system in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1466. System 1466 includes a transdermal delivery device 1468, which can be configured similar to device 1448 shown in FIG. 109, a sensor 1470, which can be any one of a plurality of sensors to measure various attributes of a body, such as oximetry, heart rate, blood pressure, glucose, and the like, and a sensor display or sensor controller 1472. Sensor controller 1472 can be configured to communicate with device 1468 to provide feedback to device 1468, which can then use that feedback to increase or decrease the rate of drug flow in a drug container to the patient or subject.

FIG. 111 is a view of a transdermal delivery system in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1474. System 1474 includes a support 1476 configured as a headband, on which are positioned at least one passive or active transdermal delivery device 1478, 1480, 1482, and 1484. Transdermal delivery devices 1478, 1489, 1482, and 1484 are configured to be replaceable.

FIG. 112 is a view of a transdermal delivery system in accordance with an exemplary embodiment of the present disclosure, indicated at 1486. System 1486 includes a support 1488 configured as a headband, including at least one passive or active transdermal delivery device 1488 positioned thereon.

FIG. 113 is a view of a transdermal delivery device in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1492. Similar to the device of FIG. 46, device 1492 includes an annular drug container or ABTT interface 1494 with a central opening 1496 in which is positioned a circular thermoelectric device 1498. As shown in FIG. 114, this configuration is advantageous because heat is distributed uniformly throughout drug container 1494, and drugs from drug container 1494 flow over a larger area than in designs of a similar size where the thermoelectric device is annular and the drug container is positioned in a central opening of the thermoelectric device.

While the present disclosure has been focused on humans to this point, animals have a similar, though less effective, passage between the brain and the surface that is described as an intracranial thermal path (ITP). For example, FIG. 115 shows an animal, such as a dog 1500. Dog 1500 includes an ITP (not shown) that extends from the dog's brain to an ITP terminus 1502 positioned adjacent to an eye 1504 of dog 1500. As the disclosed embodiments presented herein benefit humans, modifications of the devices presented herein can be modified to interface with ITP terminus 1502 for benefit to animals. For example, FIG. 115 shows a transdermal drug delivery system in accordance with an exemplary embodiment of the present disclosure and indicated generally at 1506.

Animals may have fur and fat insulation that reduces thermal conductivity, shifting the position of the equivalent of ABTT terminus 10 in animals to ITP terminus 1502, which is represented by an area of transition skin-mucosa located in the corner of the eye, frequently adjacent to the tear duct and caruncle or conjunctival surface and referred to herein as the transition area. In some species, such as canines, felines and other predators, the transition area or ITP terminus 1502 is located in the anterior or medial portion of the corner of the eye; in swine, ITP terminus 1502 tends to be located in the posterior or lateral corner of the eye; in ovine, bovine and equines, ITP terminus 1502 tends to be located in the anterior corner of the eye; and in primates such as chimpanzees, ITP terminus 1502 tends to be located in both the medial corner and the lateral corner of the eye.

In the exemplary embodiment of FIG. 115, transdermal delivery system 1506 includes an ITP interface 1508 configured to include a drug container 1510, which is configured to interface with ITP 1502, and a thermoelectric device 1512 configured to heat or cool the drug in drug container 1510 and/or ITP 1502 to control the permeability of the drug. Typically, because animals frequently object to the presence of objects near their eyes, transdermal drug delivery system 1506 includes a harness 1514 for attachment of drug delivery system 1506 to head 1528 of animal 1500. Harness 1514 is configured to position transdermal drug delivery system 1506 over ITP terminus 1502. In the exemplary embodiment of FIG. 115, thermoelectric device 1512 is configured to be connected to a pack 1516 configured to be positioned, attached, secured, or mounted on animal 1500 to provide a location for one or more batteries 1518. Batteries 1518 are then connected to thermoelectric device 1512 by, for example, wires or a cable 1520 extending between batteries 1518 and ITP interface 1508. Transdermal drug delivery system 1506 may include a controller 1522 configured to operate transdermal drug delivery system 1506, and controller 1522 is configured to be programmed, adjusted, or set by a separate electronics device 1524, which can be wirelessly or through wires or a cable 1526. Separate electronics device 1524 can be a device specifically configured to program, adjust, or set transdermal drug delivery, or it can be, for example, a cell phone, laptop, tablet, watch, or the like.

FIG. 116 is a view of an animal wearing another transdermal delivery system in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1530. System 1530 includes an ITP interface 1532 positioned on harness 1514. ITP interface 1532 includes a drug container 1534 configured to be positioned on ITP terminus 1502 when animal 1500 wears harness 1514.

FIG. 117 is a view of an ITP interface in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1536. Interface 1536 includes a drug container 1538 configured to interface with ITP 1502 when harness 1514 is positioned, attached, mounted, or located on animal 1500.

Retention mechanism 1550 includes a retention plate 1554 configured to swing or rotation on a pivot pin 1556. Harness 1548 further includes a receptacle, opening, cavity, or the like 1558 configured to support a drug module 1560 of ITP interface 1546.

Drug module 1560 includes a base plate 1562, a drug container support 1564 connected to base plate 1562 by a bias spring 1566, and a drug container or absorbent material 1568 positioned or supported on drug container support 1564. When drug module 1560 is positioned and retained in receptacle 1558, bias spring 1566 presses drug container or absorbent material 1568 against ITP terminus 1552, permitting drug to flow from drug container or absorbent material 1568 into ITP terminus 1552 and then into the brain of the animal.

FIG. 121 is a view of a transdermal delivery device positioned on a head of a subject or patient in accordance with an exemplary embodiment of the present disclosure, indicated generally at 1570. Device 1570 includes a headband support 1572, and one or more face extensions 1574. Headband support 1572 is configured to contain a drug 1576 positioned along a forehead area 1578 that, when headband support 1572 is attached to forehead 1578, is in contact with portions of frontal vein 14 and supraorbital vein 18, and, depending on the size and configuration of headband support 1572, possibly superior palpebral vein 16. Headband support 1572 includes a strap 1580 configured to encircle a head 1582, thus securing headband support 1572 to head 1582. Face extensions 1574 are configured to contain a drug in zones, regions, or portions 1584 that extend down the sides of the nose and onto the cheek area, thus covering a portion of angular vein 20 and extending into the region of facial vein 22. Face extensions 1574 comprise preferably convex or comma, boomerang or banana shape configuration with nodes or ABTT interfaces 1586 that will allow nodes 1586 to conform closely to the special topography of ABTT target area 10 and associated veins. Face extensions 1574 contain one or more drugs and are configured to fit precisely in the medial canthal area adjacent to the medial corner of the eye in the superomedial orbit, where ABTT target area 10 and the convergence of four veins 14, 16, 18, and 20 is located. In an exemplary embodiment, each face extension 1574 can include a strap (not shown) that extends beyond the facial/angular vein area to wrap around the head below the ears to fit each facial extension 1574 securely to the face. For both headband support 1572 and face extensions 1574 of device 1570, the opposite ends of strap 1580 and straps attached to face extensions 1574 are configured to be fastened to one another to form a secure fit. In an exemplary embodiment, strap 1580 may be fastened using a hook and loop arrangement, but may also use snaps, buttons, ties, hooks, adhesive, or other fastening mechanism, device, or apparatus. Headband support 1572 includes a strip of a fastening arrangement (not shown), which in an exemplary embodiment is a hook and loop arrangement, located in a region at the center of the headband support 1572. When worn by a user, the fastening arrangement will be located on the forehead directly between the eyebrows. Face extensions 1574 include a mating fastening arrangement (not shown) located on an upper end 1588 that, when positioned on the face of a user, is located above the bridge of the nose. The fastening arrangement of each face extension 1574 is configured to mate and attach to the fastening arrangement of headband support 1572. Once face extensions 1574 are attached to headband support 524, the assembly forms transdermal delivery device 1570, which is one mask-like structure to cover vital areas related to ABTT 12. The fastening arrangement of each face extension 1574 is smaller than the fastening arrangement of headband support 1572. This size differential allows each face extension 1574 to be adjusted by moving face extensions 1574 left or right, or up and down the face. This adjustable configuration allows transdermal drug delivery device 1570 to adapt to fit many different face types and shapes. For example, some people have longer faces or broader noses. With an adjustable fastening arrangement such as hook and loop, and two separate portions, i.e., headband support 1572 and face extensions 1574, transdermal drug delivery device 1570 may be suitable for any number of wearers that have innumerable anatomical differences. It should be understood that device 1570 may include thermoelectric devices configured to heat the drug or drugs in positioned in device 1570.
